depression
"Xanax is a great medicine when taken moderately and carefully. I take 2 to 4 mg every once in a while to relieve stress, anxiety, depression, and boredom.  Although alprazolam is incredibly effective I must warn that it is also extremely dangerous when taking too much or, if taken for a long period. Secondly, it works great for panic attacks but don't forget that if you stop taking the medication your stress and anxiety will return with a brutal vengeance. "
