Panic Disorde
"I was suffering from nocturnal anxiety attacks for several months, but Xanax helps me get a good night&#039;s rest most of the time.  0.5 mg gets me to sleep, but 1 mg knocks me out for the whole night.  I do not find that I wake up groggy or experience any other side effects, although I am wary about withdrawal symptoms.  It&#039;s a great medicine overall though!"
