Just wanted to let you know that I've had some great success taking Inositol. I think I read about it here (?).
I noticed it worked within a couple of days (maybe sooner). I'm taking 730 mg twice a day (with food) and the tics are much reduced. I'm finding I don't need to take the clonazepam/Klonopin. I'm going to start taking it 3x a day, as recommended and see how much it might help.
I also take a super B-complex, time-release. Not sure if that works with the Inositol....I take a bunch of other vitamins, minerals too.
Hope it works for others!
