what you are describing is not the Xanax it is things like antidepressants and mood stabilizers that are causing this the fact that he is taking so many in a day points too these things Xanax is basically high speed valium it is given too people with ptsd for agitation like the sound of a helo going over the house or being in a large noisy crowd it knocks you on you're ass QUICK
if anything you should be glad for that one he is taking the last thing he will do on Xanax is run around waving things please don't ask me how I know but believe me I do.
