anxiety
"I started off at .50 mg then to 1mg before bed.  I had many issues going on in life and I was having trouble falling asleep.  This helped in the beginning, but my dose is going up and up. I admit, I take this more than I should, so I understand there's an addictive nature to this.  Just be careful, and talk to your doctor if you notice that.  The best part of this drug; I get a good night sleep and I'm not waking up 3x a night."
