anxiety
"I take about 2-4 mg a day of Klonopin. It makes me tired sometimes, but it works better than the anti-anxiety (depression) pills like Paxil and Prozac. I'm a recovering heroin addict and doctors hate to treat you like a regular patient.  I've been clean now for 4 years but my addiction will follow me for the rest of my life.  If that's the penance for staying clean, I'll take it."
