I prefer the hydro's as well. I was prescribed the Xanax for panic attacks and was not even aware that I was addicted. It just snuck up on me. They do not give you a high like the hydro's but they did help to calm me down. Unfortunately the withdrawal's from them are horrible...right now I feel like I am having one long panic attack.
Even though our situations are reversed ( I think hydros are much worse, zannies don't scream my name), I think it's a good idea to take care of yourself the best you can. Try all three(sleep, eating, vitamins) couldn't hurt.
