Hi, I've been on a low dose of xanax for years, also some dalmane as needed for sleep. Is it possible on only .5 mg a day I am addicted? I am having horrible anxiety now since I've cut back, headaches too. Also I am a drinker, avg 20 beers a week, which that too trying to curb. My new doctor has reduced me to taking 1/2 of my .5 for a week then none.
