In my late twenties I quit drugs and went to college. Began making odd sounds, grimaces, odd word phrases. Diagnosed with adult onset tourettes syndrome. I may have had it for a number of years, but masked by the drug usage. It has been shown to be a form of epilepsy that only involves part of the brain. If I get enough sleep, don't drink or smoke pot, and most importantly stay away from stress, it doesn't act up. If I do let myself get rundown and add stress to the mix then all bets are off. It is serious enough that people ask if I am OK and that the hand and arm contractions look like they hurt. Being in a room of straight, church types or with the wife's family can do it. Of course worrying about having to be in that environment sets up the stress part. The worse is when I can feel it starting and try several techniques involving hand gestures (counting while speaking, gesturing in an acceptable but overly aggresive way etc.) Every one wonders if I am a bit crazy. If I get really flustered I succom to short outbursts of coprolalia. I never lose consciousness like you seem to have. Mine is most definitely influenced by stress and my gender fluidity - at least indirectly. I hope that is the only one you ever have.
