I have been on xanax though for 4 years. And I am not on any other medicine. I am hoping its from slowing down the xanax. But who knows im not really CRAZILY slowing it down enough to really have withdrawals, at least I dont think? I just hate the feeling in my eyes like they cant stay focused or something, they like vibrate, or like are moving, but I videoed my eyes and I notice no movement.
