I have found it does help me but there is what I call a success- window to it. If I take it more than an hour before I go to sleep, if something comes up and I dont get to lay down at the time I had planned (which, with 6 kids still living at home happens more often than u can imagine) then it does me no good at all! I have tried otc sleep meds like tylenol PM for instance and they have a weird anti-effect on me. I feel every nerve in my body tense up and the slightest little ache or pain I have seems intensified 100 times over! One night I had a PAPER CUT for cryin out loud and it felt like my thumb was sliced half off! I couldnt get to sleep at all. Took only about 3 nights of trying before I ditched the idea of using those.
