So, having had 3 cans of beer today--12 oz cans, 5%abv--my understanding it hat the average human body can metabolize 1 such drink/hour. My doctor prescribes me Xanax (alprazolam) for acute anxiety attacks. I do not take it often, maybe .5mg 2-3X a week. I would never risk drinking and taking benzos together, but now it has been three hours since my last can of beer, six hours since my first. If i understand correctly the alcohol should be metabolized. Is it safe to take .5 mg xanax. If my doctor worked sundays, I'd ask him. Please don't cite me AMA generic information.
