Shorty, I was wondering what size dose you've been given? I was prescribed 1 mg when needed, but I find that even 1/2 mg works for me. Dr. told me to try 1/2 mg to see if made any difference. I think it does, but on really bad attacks, I take 1 mg. I have not noticed any side effects, besides feeling really relaxed, which I need when I have that real bad anxiety feeling. But I never noticed it to help my ibs problem, although I only take once in a while not on a steady basis, maybe I might notice then.
