"i get intense panic attacks. xanax is very effective at working quickly to stop a panic attack. it saved my life, until after a few months i tried to stop taking it and got horrible withdrawals. i felt like i was dying, my anxiety was worse than it had ever been in my life, high blood pressure (and mine is naturally low), tachycardia, hallucinations, tremors. i hope anyone considering taking xanax takes it at a low dose and not daily. if daily, do not quit cold turkey.
