I don't have any mental illnesses, but I think legally I'm classified as disabled since I have severe Tourette's, OCD, and Aspergers. I was on medication for many years for my Tourette's to control my twitching (Clonidine) and it did absolutely nothing beside making me feel like a zombie and sleeping all day. I am now medication free and have been for the past 3 months and my twitches are still the same with or without the medications. It really shows how for some people medications work more than on others. Also for all of you battling your condition/condition(s): best of luck!
