To Chemar and britmom (and anyone else who can help),
Thank you for your replies, I posted another response but I didnt see it on here, so I apologize if this is redundant. The carnitine you both use is L-carnitine or acetyl-L-carnitine. Been doing some reading about how they are different and to not switch between the two. And from what you have said, it sounds like you treat your child with the L-carnitine for a couple of days and the vocal tics remit. And then you keep them on it for maybe two or three other days. You stop the supplement and then the tics remain absent for a period of time. And it sounds like a fairly long period of time before they return and you repeat the process. Is that right? Thanks again.
Kevin
