"i have had trouble sleeping for at least 10-12 years.  my brain doesn&#039;t seem to shut down.  otc like benadryl has no effect on me at all.  after many trials, my doctor found than a combination of clonazepam and tranzadone work great for me.  they two don&#039;t make me sleepy at all but instead calm down my brain activity in order to go to sleep.  i take them about two hours before going to bed.  in addition, i found that the brand name qualitest for clonazepam works better than teva.  i&#039;ve been using this combination for about three years and they work great."
