Bests & Worsts Reviews from Amazon

I awaken multiple times throughout the night and have difficulty getting back to sleep. I bought this product because it was supposedly developed by a neurologist, so I thought there might be some science behind it. I took 2 capsules the first night, and they had no effect on my sleep. Directions state that one can increase the dose to 4 capsules if needed, so on my second night I took 3 capsules. Still no effect. Next night, 4 capsules, same result. A complete waste of money.
