Life-changing Aid For A Heavy Problem Drinker
I’ve had intense anxiety (social and general) for as long as I can remember. Years ago I turned to alcohol to help—a couple of drinks when I felt anxious, or before a social situation calmed everything down, and I felt as though I could manage. But it quickly spiraled out of control to the point where I wasn’t drinking and getting drunk, but instead “dosing” throughout entire days and evenings. The moment I’d try to stop the world would come crashing down and it became a choice between feeling “normal” by drinking something, or dealing with nonstop racing heart, shortness of breath and severe depression. Well the latter was absolutely horrible to live with, so I kept choosing the former. I was hiding liquor bottles in the house so I could pop back to a room and take a nip the moment I would start to feel overwhelmed. Obviously this wasn’t sustainable. My epiphany occurred when my senior dog had a seizure, and to cope, I begged my partner to go and pick up a pint of alcohol, just to get through the worry and fear (she’s okay now). I realized SOMETHING had to change. I read and did research and decided to try L-theanine. This brand was the first brand I tried. I began with 2, and then upped the dose each day until I found the perfect “sweet spot” for me at 1200mg*. That seems like a lot, but my brain had been depleted of natural anxiety defense for years. The day I took at the amount for the first time changed the entire course of my future. For once I was able to breathe, to think clearly, to feel calm and normal without a drop of alcohol. The effect lasted nearly 12 hours, and that night I slept like a baby. I tried it the next day, when that familiar anxiety and urge to drink crept up... and it worked again. Within the hour, my heart began to beat normally, and I was calm and content, and once again drifted off to sleep that night genuinely looking forward to waking up (a rare thing when you drink every night). So far I’ve been sober for three weeks, and I feel amazing. There are no sedation, stimulating or uncomfortable side effects, it kicks in within 30-60 minutes (depending on whether you’ve eaten), and one dose lasts me 12+ hours. I have zero urge to drink, I sleep great, my mood is amazing, and my typical ADHD brain is clear and focused! It’s my belief that when my brain finds equilibrium and begins to produce its own dopamine again (which I’ve read takes about 6 months for alcoholics and problem drinkers) that I’ll only need the L-theanine on difficult or stressful days. For someone who spent every waking moment suffering the pain of severe anxiety, I could really cry from joy for this mental, physical and emotional reprieve. For once I’m truly excited about the future. *1200mg is a high dose, and over the recommendations based on studies looking at changes in alpha waves (200-400mg). I am not a doctor or health practitioner, nor am I suggesting people follow my dosage right out of the gate. If you’ve never had substance abuse issues, you likely will not need such a high dose. Research and consult your doctor before adding any supplement, especially if you intend to take more than the recommended amount. I began with two (the highest recommended dose) and did not increase that dose until 24 hours later. I stopped at 1200mg because that was the dose that gave me the relief and results I was looking for; I do not intend to exceed that amount for myself in the future. Edit to Update: it’s over a year later, and I no longer drink, nor do I need to take Theanine (even in social situations!). My brain is clear, I’m genuinely happy, and so so glad I discovered this. Quitting drinking can be hard, but this absolutely saved my sanity and my life. I still will always keep a bottle on hand, and I can’t recommend it hard enough for folks desperately looking for aid. Good luck out there friends!

Works great !! Very Satisfied !!
I am very satisfied with The L-Theanine 200 mg . I actually bought it to take in the morning but I had to switch to night time because it really relaxed me and made me too tired. I’m happy to say I’m finally sleeping. I would wake up around 3:00 AM off and on until 6:00 am when it was time for me to wake up. I felt exhausted all day. I had no energy and was in bed for 7:30 pm . I have been taking this supplement for a week and I feel so much more energized during the day because I’m getting restful sleep. I feel by brain is finally shutting off which has been a struggle for me. I will definitely keep ordering this supplement. I will also say you can tell it is great quality because you can smell them when you open the bottle.

100% game changer
Took my first dose with about 80mg of caffeine this morning. Holy, I cannot believe how effective this product is. I forgot I even took it but then throughout the day I was thinking like wow I’m having a really good day? Super focused yet calm, present, and just overall locked in. All things I’ve been struggling with for years. I couldn’t recommend this more. Capsules are easy to swallow as well and the inside of the bottle has a pleasant but mild coconut scent, likely from the coconut oil it’s manufactured with.

Works!
My therapist recommended I start taking 200mg of L-Theanine, I was irritated for no reason at my husband. Was about to travel and spend time with family. She said to start it immediately, so I don’t bite anyone’s head off. I’ve been taking it ever since and I am more calm and focused and do not get irritated with people because they are breathing. Only 4 stars because the pill is rather large.

Great for calm focus — I’ve been using it almost a year
I’ve been taking this for almost a year and it’s been consistently helpful. I take it with my morning coffee before work and it keeps me relaxed and focused without the caffeine jitters. It also mixes smoothly every time, which I really appreciate. Plus, the brand feels very natural and organic. A simple, steady way to start my day feeling more Zen.

Finally Sleep!!!
Okay this is the first review I've ever posted on here. I've been an Amazon Prime customer for years. I make tons of purchases on here (133 in the last six months) but I've never left a review until now. I decided to write this review because this may be the best product for me and life changing product ever! Also, I wasn't given any kind of discount or promotion for this review!!! I have suffered with insomnia off and on for years. The main contributor has been the fact that I've had to do lots of on call and shift work. I've tried virtually everything at one time or another from OTC antihistamines, herbs, minerals and other amino acids like kava, valerian, magnesium, passion flower, tryptophan, melatonin, zinc, ashwagandha, hops, chamomile on and on with no real luck. I have also tried prescription sleep medication like Ambien, Lunesta, Sonata, Valium, Rozerem to name a few. Ambien works pretty well, and I have continued use with it over the years off and on but really wanted to eliminate it all together especially because I'm very limited on how often I'm allowed to take it due to my employment. I also don't like the idea of having to take any type of medication habitually and that's not what it's intended for. My current employment also forces me to change back and forth from nights to days and vice-versa which makes it impossible to get into a good sleep routine. On a whim after reading some reviews, I decided to give L-theanine a try for my sleep issues. I had read that some people take it during the day and some at night. Some people combine it with coffee for more focus, some use it for anxiety, others sleep. It sounded like different people used it for different things. I was interested in it only to help me with my sleep (primarily falling asleep). I know individual body chemistry can play a huge role in the response each person has to different medications/supplements. I was just hoping that this amino acid would finally be the solution I've been trying to find for so long. I went ahead and ordered it and all I can say is WOW!!! I've only been using it for five days, but my sleep has been amazing. I personally take it about 30 minutes before bed. I can actually feel the effects from it in about that time. For me it feels slightly dissociative. I don't necessarily feel sedated but I don't linger on any thoughts. I almost feel like I'm wrapped in a blanket and my mind goes clear or black. Any thoughts that I start to have flash away. I know that sounds weird, but it's the best way I can describe it. The days before I tried it I had been working nights and wasn't able to fall asleep until around nine in the morning. That is so frustrating. I would lose not only the time laying in bed at night but also half the next day. As soon as I started taking these around 11:30 PM I was out sometime between 12:00-1:00 AM every time. I have woke up a couple nights, but I was able to go back to sleep. I've been able to get a minimum of seven hours of sleep every night I've used these. I did try a different brand 100mg dose, and it did not work for me. I always like to use the lowest dose possible of anything. It looks like I will be continuing with this brand and dose. Time will tell for me if this supplement/amino acid continues to work the miracle it has the last few days. I can honestly say I'm ecstatic at the results so far!!! Obviously this won't work for everyone (nothing does) but this has reacted great to my body chemistry and accomplishing what I want it to (deep sleep with fast onset). I definitely recommend trying it for anyone who has suffered insomnia/fatigue like I have. I wouldn't wish that on my worst enemy!!!!!!!!!

If you like a morning coffee, add this
Great stuff, love it with a cuppa joe. Makes me alert, but relaxed with that combo. Kind of middle of the price range, there are some more expensive and less, but I don't trust the stuff that is dirt cheap. Google says suntheanine is patented top tier stuff, and I agree.
