Anxiety
"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. "
