I take Ambien for insomnia and Xanax for anxiety during the day. I am also on Lithium and Wellbutrin for Bipolar II. My GP had prescribed the Xanax. Psychiatrist says no more Xanax, says you can not take it and Ambien together. Obviously I don't take them TOGETHER, but he won't listen. It was going just fine until Dr. Shrink found I had both drugs. I need something to manage the anxiety attacks I get at work 2-3 times a week. Was wondering if I could use the Ambien in place of the Xanax?
