Review: 303 is the best, hands down! - Formula 303 is an amazing relaxer product alleviating multiple ailment's for me. Those complications consisting of general pain relief helping with the relaxation after a long day's work. In addition to helping with relaxation, it helps with my (non-diabetic) neuropathy, focus, and my quality of life outlook. It's definitely worth the price, even though I've run out and can't afford to buy more right now. Hopefully Dee Cee will see my review and help me out with my next bottle (250/count) purchase. Regards, Brandon
Review: Formula 303 300 - 0 stars for the online instructions. Worked well for my injured back after I took half a bottle following the instructions online (take 2 wait 2 hours take 1 or 2 more wait etc). It was difficult to reach a therapeutic level to achieve any relief. After that. I just started with 5 and found it to be an excellent starting point. It helps immensely with my whole body spasms and sleep. I have found that 7 or 8 Works well for sleep so that I'm not constantly waking with cramps. Just for a reference, my weight is approximately 150 pounds. That doesn't necessarily mean that a 300 pound person will need 14 to 16. I would still recommend starting with 4 or 5 from what I have discovered over the last 2 years. Even my 260 pound fishing partner only needed 4, but he doesn't have the nerve damage that I have, hence, I have needed a slightly higher dose. Good luck, and be cautious, other medicines and supplements can interact with this supplement, hence the name nature's Valium. I hope this helps.

### ⭐⭐⭐⭐⭐ So relaxed, I can sleep thru my alarms
*by S***S on June 22, 2016*

I work in the film industry as a boom operator. In a nutshell, I spend a great deal of my 12+ hour long days with my arms over my head. A few years ago I was booming a scene where the Director kept making us do the scene over and over again without cutting. I had the boom extended out nearly 25 feet with one of the heaviest microphones inside of the full wind protection rig at the end of the pole for many, many minutes. It was during this scene that my shoulder started hurting terribly. For years I've felt pain daily and ibuprofin only helps a bit. I've tried muscle simulators (Tens machine) and various kinds of professional massage techniques from many professionals and they help but are expensive. I make excellent money but feel it getting worse over time and know my time in this career will be short if I don't do anything. I have a comfortable bed but it's not comforting enough to relax me into full REM rest at night. Desperate I turned to Amazon and ran a search for muscle relaxing pills then sorted for those with highest consumer rating which brought me to this product. When my call times put my morning commute right in the middle of rush hour, I leave my house early and sleep inside my car in crew parking. That means that I still get up at 5AM to drive in then sleep in my car a few hours. Don't judge, it works for me the way I do it. The pills arrived around two weeks ago and it says the dosage is two pills. I eagerly took two about 5 hours before I had my alarm set. I laid down and was out a few minutes later. The next thing that happened was I was dopey and looking at the window with sunlight behind it. I flung awake and noticed that I had overslept by 2 hours. I left the house minutes later and endured a 95 minute commute instead of the 25 minute commute it would have been if I left at 5:20AM as planned. I checked all my alarms before leaving and all 4 had been set. I just turned them off in my sleep. That night I made a point to set each of my 4 alarms again then took my two pills. Guess what? I overslept by 2 hrs 15 mins and had to endure a morning commute 4X longer than normal again. Yet again, I turned off my alarms in my sleep. That was a Friday so that night I went to sleep again after taking two more pills. Awesome! These pills work quite well for me. I've since learned that 1 is all I should take on a work night but 2 works great any other night. I'm nicely relaxed when I wake up and my muscles aren't sore for the first few hours in the day. Side note, as I go to sleep at night, I coat my shoulder with a heavy amount of Biofreeze. The combo fully relaxes and helps reset my shoulder. Before I started taking these pills, it soothed the muscle but didn't relax. I'm very pleased with these pills and plan to continue to use them.
