Insomnia
"I&#039;ve tried several options, over the counter, homeopathic, and prescription in a quest to deal with transient insomnia which typically triggers a worsened depressive mood (kind of a negative feedback loop). Ambien was one of the first I tried. It works very quickly, has very little hangover, but did not always KEEP me asleep. I usually wake around 4. 

The bad: tolerance, &quot;sleepwalking,&quot; waking up in my roommates bed with no memory of how I got there. Be cautious, if you live with other people let them know you&#039;re suffering from insomnia and that you are taking this medicine. My roommates reported me seeming completely coherent while sleepwalking%u2014 it can be more problematic than mere &quot;sleepwalking.&quot;"
