My PCP and I decided together to use ambien for sleep because I need the Xanax to do what it needs to do when I am in in throws of fighting off the urges to binge/purge or SI. It was best to keep the sleep meds and the anxiety med separate. The Xanax also has a half life in the body and I could still wake up at 3am while the ambien would keep me asleep. We did try Trazadone but I was so drugged still in the morning plus it increased my suicidal thoughts and made me feel more depressed.
