Wow, I can't imagine that much Xanax. I went into an inpatient rehab facility last year for alcoholism. I needed to detox. I was there for six nights and seven days. I was also taking Xanax, but was only taking two to three mg. per day. They took me off the Xanax too. It was, bar none, the hardest thing I have ever done. I slept about two hours the first night I was there and then not a wink for the next five nights, even though they administered some type of drug to help with the withdrawal. I don't think I had any alcohol withdrawal symptoms, but boy howdy, did I ever have a rough time getting off the Xanax. I thought it might kill me, but I just had to have faith that they knew what they were doing. I have since relapsed on alcohol, and I can't seem to go more than a few days without it, even though it's just about corroded away my esophagus, but I haven't touched any anti anxiety drugs since July 3, 2007, and I hope like hell I never do. I am so grateful to be off the benzos. But like I said, it was the hardest thing I ever did.
