question: Hi. I m a 21 year old female, 5 , 125lbs. I m prescribed 0.5mg of Xanax to take as needed for anxiety. I m also prescribed a daily 50mg of Pristiq for depression and anxiety. My psychiatrist told me that the general rule of thumb was to allow about 6 hours before or after taking Xanax if I want to consume any alcohol at all. I had 1.5 beers about two hours ago and was wondering if it would be wise for me to take a Xanax right now. (I wasn t anticipating needing to take Xanax tonight but had an unexpectedly stressful even arise.) Thanks
