You need to seek medical advice immediately for xanax detox, you are at high risk of seizures and even death! Take care and please go to the ER.
I tapered off Xanax only about 2 years ago. Was on it for about 8 years, 1.5 mg/day. It was very difficult. I can't imagine cold turkey off of 2mg/day. That can cause seizures...they had me on an anti-seizure med for that reason while I was tapering. I remember getting "electrical jolts" every now and then, leg cramps, anxiety of course. Good luck, that is a hard one to get off of.
