Clonazepam
"I started taking this medication to replace Xanax in the early 90's.  I am now 44 and have been on .5mg-2mg/day of this drug for almost 25 years.  I also take sertraline (Zoloft) and buspirone (Buspar) for my depression, anxiety, panic, and OCD- all of which I've suffered with since childhood.  The Clonazepam has been a wonderful drug which has allowed me time free from the agony of anxiety.  It has also caused me problems with drowsiness and memory.  Withdrawal has been manageable on a couple of occasions.  I am currently on .25mg/day/prn and am trying to get off of it completely per my MD.  The couple of time I came off of it precipitously to avoid drug screenings at work were some of the worst times of my life."
