im not a doctor but I can relate two separate incidents to you that will cause me to stay the hell away from xanax while drinking. THEY CAUSE VERY SCARY BLACKOUTS!!
On a normal sunday afternoon, I took two xanax to help ease some heavy anxiety i had been experiencing lately... i felt fine all evening, and later had about 2 1/2 glasses of wine after dinner. my boyfriend went to sleep and the last thing i remember is that i wanted to stay up and watch a movie. next thing i remember is waking up in my bed the next morning. my boyfriend had found me passed out on the couch and had to carry me to bed. also, i checked my phone logs and i had sent crazy text messages to all sorts of people up until 4am and they didnt even make sense - i was so embarrassed, I dont remember a thing.
Incident two - the following night... mind you, i had taken the xanax sunday and thought that for sure it was out of my system the next day. i went out with a few friends to the bar monday night and had about 5-6 beers which is way less than normal and my friends said that i was getting really emotional about all sorts of things by the end of the night and was crying and that i just passed out in mid-sentence.
ive taken other prescription medication before while drinking, but nothing has ever f-ed me up or scared me as much as xanax did. i will never take it again, even for anxiety. i was so embarassed about my behavior around my friends (they said i didnt act drunk, i just acted really "messed up") and the fact that blacked out and dont remember a thing. All i can say is please be VERY VERY CAREFUL! I NEVER KNEW THIS DRUG WAS SO POWERFUL!!!
