Hi , I Was Prescibed Clonazepan (.5) Milligrams. The Psychiatrist

Hi ,
I was prescibed clonazepan (.5) milligrams. The psychiatrist I saw felt it may actually be better if I took this dosage twice a day. However, I was afraid of being even more addicited, as I know how strongly addictive this drug is. My psychiatrist was fine with that decision. I am also on anti-depressant medication which has been helping greatly.
Now, the problem is that I guess I have been taking a few more here and there than usual. In other words, I'm about twenty days away from my pharamist being able to refill my current prescription, as she says it is a controlled substance. I don't, by the way, usually go overboard on my medication: this is unusual.
Well, I have problems with anxiety anyway and I am truly scared to death of going into total withdrawl for several days. I'm not sure I can handle it. Anything I can do? Thanks for your help
