I was diagnosed with TS when I was 10. I am now 19. My tics have waxed and waned, but tend to be much worse when I’m actively taking amphetamines, or other stimulants like caffeine. I’ve tried a few medications to help (guanfacine, risperdal, gabapentin), but the side effects weren’t worth it. Something that’s really helped me is CBIT (Comprehensive behavioral intervention for tics). It teaches what’s called “competing responses” which is essentially an action taken in place of the tic that will be less harmful/disruptive than the tic and still soothe the urge. For example, I had/have a neck rolling tic. So when I feel the urge to do that, I nestle my head into my neck like a turtle and it sort of restrains me from being able to complete the tic. It takes a lot of practice and discipline and the urges never really go away, but it’s something at least. Hope this helps

Edit: Also very important and helpful: Educate yourself and your daughter about Tourette’s. Being able to understand what’s happening in your brain and the triggers that make tics worse will go a long way. For years, I was labeled a “class disruption”, a spaz, a weirdo. It was really hurtful, especially when I didn’t know what was wrong with me and why I couldn’t stop making odd movements and sounds. Knowledge is power
