after having a tightness and chewing in my jaws and side of my head for several weeks and only being on lamictal I did a search for that with lamictal......what I found was TD,,it fit all my symptions perfectly ...I believe the geodon caused it the xanex masked it and when I got off both it reared it's ugly head...it has lightened some I know longer chew so hard to make my teeth bleed I just have the tightness and a tongue that will not stop pressing againt my teeth.and a twiching of my left thumb...after reading a lot I am pouring on the B-6 and melation .and plan on getting fish oil...I will beat this but I really do convent your good wishes and prayers......maybe now you see why...
