Klonopin can be prescribed for a number of reasons. It can be prescribed for anxiety, or for epilepsy. I take it for anxiety related to my OCD. The first couple of weeks when I took it, I was tired and fell asleep for a couple of hours nearly everytime I took it. It no longer makes me go to sleep, but when I take it, I can definately tell that I am clamer than when I do not. As for withdrawl, I have never experienced any withdrawl symptoms when I didn't take it, but everyone is different. i hope this helps.
