When my daugher was 8 years old (she is 21 now) she had motor tics for about a year (shoulder shrugging) and my son who was 11 (he's 23 now) had both motor (eye squinting, blinking) and vocal (coughing) tics. I went to a homeopathic doctor who was also an M. D. And he gave them Baryta Carbonica 200CK. They each had four globules (little round balls) placed under the tongue on an empty stomach (they did not have anything to eat or drink 2 hours before and two hours after administration). The globules dissolve under the tongue in less than a minute or so. After about 4 weeks, both of them have been tic free. I still keep some of the remedy on hand just so that if the tics ever come back I'll know what to give them. The remedy can be ordered online - and it doesn't cost much.
