Tourette's and the Army?

I've always struggled with tourette's when I was a kid, I had real bad facial and head tics/twitches that I couldn't control. I took medicine that seemed to help and hide the symptoms. A little over two years ago I stopped taking the medicine and felt perfectly fine, I kinda umed it went away. However, a year ago I enlisted in the army and didn't mention the tourette's partially due to recruiter influence and cause I had umed it went away. I know that alone can get me in trouble, but the problem now is I deploy to Iraq in a few months and it has been acting up quite a bit. It acted up once in November, 2008 while i was in AIT but went away after a few days, but I paid no mind. However lately its been acting up a lot more, I believe do to the stress. I'm a gunner for a maneuver platoon and I'm really worried about it affecting the safety of both my battle buddies and myself. Does anyone know what might happen if I go to my chain of command about it? Would I get discharged or simply recled? If anyone could help it would be greatly appreciated.
