I think I have a vocal and nervous tic. A lot of times I have uncontrollable movements with my fingers and legs at the same time and sometimes with other parts. I also have an uncontrollable urge to say things that are out of context, like "chicken turkey" or i just say "such". I try not to say it in front of anyone else I just say it in front of my closest family. It has been a problem for me for many years. I have trouble reading and listening to lectures and paying attention because of the way i move my fingers and legs. Is there anything over-the-counter I could buy that would help?
