Hi, First of all why you are taking diazepam..Is it prescribed or u r self medicating..Panic disorder/ anxiety disorders doesn't mean diazepam is the mainstay of treatment...I think and I advise you that this is best time you Consult a Psychiatrist for detailed evaluation and Management of the case..discuss with your dentist also..Because if you have been taking diazepam since long again we don't want withdral..ok...hope it helps. Regards
