I don't know about clonazepam, but I do have a script for xanax. It helps me tremendously. I too have severe anxiety sometimes, not all the time and sometimes find myself very overly stressed for no reason. My largest lesion was in my frontal lobe and I think that's where emotions are controlled, if I remember correctly. Sometimes, if I don't really need it, xanax knocks me out and makes me want to sleep, but I find the times where I really need it, it just calms me and helps me to be more like myself. It is nice though for help to sleep when I have insomonia. I do try and not take it too much though because I worry about the fact that it can be addictive. Some weeks, I don't take any at all, other times, I have to take it several times a week. I take a .5 mg tablet.
