anxiety
"I quit using meth a year ago and have had random anxiety, panic attacks, and an insane racing heart all the time.  Xanax and benzos make me way uncomfortable so my Dr prescribed me Hydroxyzine.  It works AMAZING for me.  If you can get the pressed pills instead of the capsules.  Sometimes the whole 25mgs makes me to tired especially if I'm at work.  With the pressed pill it's easy to just take half. I really recommend for anyone who hasn't found something else that works"
