anxiety
"Works great for short notices. If you find yourself in a anxiety situation or short notice to do some public speaking then Xanax is great for those situations.  When I take them I only take half the pill and that dose is fine for me. It kicks in about 20-30 minutes and lasts a good couple of hours at the most. Its similar to Klonopin but works faster. I recommend it for as needed use only. If its an all day thing then Klonopin is better. Just my experience with it. Others may vary."
