"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&#039;t forget that if you stop taking the medication your stress and anxiety will return with a brutal vengeance.
