Dude, I took 9 tablets at .5 mg each. That makes 4.5 mg. I also downed a dose of nyquil. Keep in mind that I'm 34 years old and I have been prescribed xanax since I was 18. I've been taking the stuff for 16 years. At one time my doc had me taking 12-15 mg/day. However, that was a while ago and I've gotten my normal dosage down to 2 mg of controlled release xanax per day. Tonight I wanted to get a buzz so I popped 4.5 mg of regular xanax. That's the most I've ever done at one time. However, I'm starting to feel light headed right now. Maybe it's just kicking in.
And by the way, I'm hopelessly addicted. My doctor basically told me that I would need to take it for the rest of my life. I have serious panic disorder.
