insomnia
"I've suffered from chronic anxiety for my whole adult life.  I haven't slept eight hours straight in probably ten years.  I had convinced myself that I was one of those people that didn't need much sleep until my mood began to change for the worst over the past few years.  I finally saw a doctor about it.  She initially prescribed Elavil which did nothing for me.  She then switched me to Trazodone which has changed my life.  My mood has completely changed.  I am more friendly and outgoing now and I feel like I have a new lease on life.  If you have insomnia and nothing seems to work, you owe it to yourself to try this medicine."
