CRAP! I can't seem to shake these wd's. Today is day 16 and I'm still struggling. I took Xanax xr 1mg nightly for less than a month and thought I'd see some kind of improvement by now. I get these waves of symptoms that start around 11am and last for 7-8 hours then they seem to subside. Fever, anxiety, depression, headache, fearful thoughts, jittery, I'm basically a RICHARD during that time. I've been told that the dose I took was relatively small but Ive also read that Xanax can cause dependence in as little as 7 days. While I'm still fighting this I can say that I think the waves seem somewhat less intense. Would anyone have thoughts about an expected duration of these wd's? Several articles have mentioned 30 days as an average.
