insomnia
"I have never experienced any hallucinogenic side effects from this drug, but I admit I've developed a nasty dependency to 100 mgs/night. It is the only sleep aid that doesn'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't going anywhere, no sleep walking, driving or binge eating."
