In my experience, to get rid of tics/tourettes, changes in food style will yield good results.
My daughter had the same issue and now she is free from the tics/tourettes
She eats soaked nuts(Almond/walnuts) first thing in the morning to help nerve function.
Completely avoided sugar. Added millets especially foxtail millet to her food to support nervous system health. Also she takes centella asiatica powder mixed along with milk at night to improve the cognitive skills.

Just my personal opinion: I would warn you about the neuroleptics that are typically prescribed for Tourette’s…the side effects are really tough, thought the meds can be effective if you can get past the side effects. I couldn’t. These meds would be Orap, Haldol, Risperdal…any Anti-Psychotics. I take an anti seizure med now that’s helps a bit. For 30 years, I took no meds because they were worse than having tics. I’ve always stayed away from caffeine, which I also recommend. And get enough sleep.
The food thing….well, that’s all anecdotal. I’ve tried elimination diets and restrictive diets as a kid and none worked.
Parents may see fewer tics, but that doesn’t mean they’re not happening. Keep in mind, as your body changes and grows, you Tourette’s does as well. So what works at 12 probably won’t at 24 or 40. Especially if you’re female..
BOTTOM LINE: don’t get medication advice here. Talk to your neurologist. If you don’t have one, you should get one.
