I didnt have tics until I was 15 and Had medication for mental health

Straight after I had medication for my mental health my tics came and they was terrible. After I stopped taking pills for my mental health , My tics reduced. I wonder if that caused them. Im 22 and I still have them but they arent bad , unless ive ate gluten as that really makes me tic really badly as its worst after ive ate gluten also stress makes them worst too. And some days they are terrible to the point some can be dangrous.
