I started zoloft a couple days ago (50mg, but will go to 100mg on 7th day), and I noticed something weird. my jaw muscles feel strained and the back of my tongue feels numb. nothing is swollen and I can eat/drink/talk just fine. Its the strangest thing. It just feels funny when I yawn (which happens a lot because zoloft has also made me tired), because it feels as if the muscles have a small delay in their relaxing. anyone ever hear of such a thing?
Zoloft has been associated with jaw clenching and teeth grinding, so I guess it is possible that is happening to you at night and you are feeling these strange after-effects when you're awake. Just a thought. If you're going to stick with the medication, you may want to try a mouth guard (you can get one over the counter at a large drugstore, online, or you can have your dentist custom fit one for you).
