tourette's syndrome
"I started with this medicine at age 11, I took it for 6 years on and off always having to up the dosage. The side effects I experienced were dizziness, drowsiness, and lack of energy. It would mellow my ticks (eyes, body, and low vocal noises) down to a tolerable level, but if I continuously took it day to day for months it would seem to stop working as well. Now I don't take anything (21 now) but natural high magnesium doses a few times a week and  it mellows me out just as well. Doesn't stop my tics completely but doesn't bother me. I don't recommend for people attending school or working in a quiet environment."
