I had a few drinks over a few hours, and then about two or three hours later, took .25mg of Xanax. I felt completely sober by the time I took the Xanax, I had actually forgotten I had any thing to drink. I take Xanax occasionally to help me sleep. I also take 300mg of Wellbutrin, b/p meds and asthma meds. I'm now afraid to go to sleep, should I be concerned?
