"i have never experienced any hallucinogenic side effects from this drug, but i admit i&#039;ve developed a nasty dependency to 100 mgs/night. it is the only sleep aid that doesn&#039;t give me cotton mouth or drowsiness the next day and works like a charm every single time.  nothing even comes close to its effectiveness. note:  it is imperative that you take it at once you are in bed and ready to sleep.  after that you aren&#039;t going anywhere, no sleep walking, driving or binge eating."
