insomnia
"I would like to point out that the generic version of this does not seem to work as well for me.  However, both do work at putting me to sleep.  The key is to not eat before taking them.  I believe it's in the recommendations that you do not eat as well but I thought I would emphasis it because it is very important as to the effectiveness of this drug.  I too have done things that the details are a little fuzzy on the next morning.  Usually this occurs when I don't go to bed and try to "stay up""
