Just thought I'd bump this thread.
I think there's something potentially very interesting here. I've noticed many times how tics seems to worsen with blood sugar fluctuations and how they tend to be calmer with a more even blood sugar.
I'm thinking of embarking on a journey, the ketogenic diet that is, and document the results in regards to how the tics respond.
Anyone with me? There's this MAD (Modified atkins diet) which is a MUCH easier version of the standard ketogenic diet. The rules are, less than 20 g carbs/day, unlimited protein and fat, ie eat how much you need to feel good.
