I have been taking zopiclone for years but not continuously (2-3 times a week). Sometimes sleep wasn’t better and I was often sleepy during the day. I tried melatonin, without success. When I saw the advertisement for the Vitoli product I was very skeptical, but I decided to try it all the same, because I was tired of the side effects of sleeping pills. I tried Vitoli for the first time this week. I started with one pill. I had no results. The next day I took 2 and slept better than I did with sleeping pills. I eventually want to go back to 1 capsule. My sleep has really changed. I can tell you that they are more effective than the chemical sleeping pills I used and without any side effects!
