Does anyone here or know of anyone who has has an issue with fluorescent lights trggering vocal tics? I get them and I usually have to turn my back and close my eyes as I turn them on until they stop the initial flashing. But I will get them if someone switches on a light without warning like a class room or office something.
I have TS and I am on haloperidol (seranace) to take the edge off them. Even though I get far more motor tics than vocal tics the vocal tics are far more noticable. The haloperidol certainly does take the edge of the vocal tics but makes little difference to motor tics, but I have learned to cope with those, except for sudden flashes and noises like the flashing with fluorescent lights.
Electronic gaming machines and disco lights can also trigger them.
