Review: Excellent Product at a Significant Value!! - I take these to assist with sleep quality. They are effective and I love that these capsules are so tiny, and easy to swallow, yet come in 50mgs. Most Diphenhydramine (active ingredient in Benadryl) come in tablets in blister packs that are difficult and annoying to open and are 25mg. These 50mg capsules are an excellent value for the money and you will not find this product at a lower cost anywhere. 1000 capsules will last me a long time, but I will likely purchase these again before I run out, as long as they are available. Excellent value for the money!
Review: A value to.assure.a.good.sleep - This is a fantastic value for.a.decongestant. that.also provides for a great sleep.experience.
