I used Xanax for 17 years cuz I had a lot of anxiety that disrupted my sleep. It worked well until I went through a manic stage a few months ago & I couldn't sleep more than 3-4 hours even with taking the Xanax so now I've been put on Trazadone & Klonopin. They are helping. I'm averaging about 6 hours a night now.--Suzy
