I've been using this product on and off for the last two years — primarily during heavy training periods — and I believe that it has really helped me.
Taking these pills results in exceptionally deep, refreshing sleep, with extremely vivid dreams. And if I do wake up in the middle of the night, I will fall back to sleep almost immediately. I can say subjectively that I seem to feel better refreshed and less sore the next day if I take this after a tough workout. And interestingly, while I usually sleep around 8 hours each night, if I take these I'll wake up fully alert after only 7 hours. I am sorry to report that I haven't experienced the wonderful sex dreams reported by some others; I'll keep trying!
A warning: I would recommend taking these at least 30 minutes — maybe even 60 — before bed. And only take them if you have at least 8 hours before you need to do anything productive. If you don't give them enough time, e.g. if you take them at midnight at get up at 5:00, they will leave you groggy and disoriented instead of thoroughly refreshed. And I can say without a doubt that these things are not placebos: I accidentally took them one morning instead of the supplement I meant to take, after a full night's sleep, and for the next 8 hours I could barely keep my eyes open.
The bottle says to take 3 pills, but I've found that 2 of them is enough for me. (I weigh 165 lbs and concentrate on running; YMMV if you're heavier and/or a bodybuilder.)
All in all, I highly recommend giving these a shot if you want better sleep and better recovery. I'm absolutely a believer.
