I'm on Cymbalta (60 mg) and Wellbutrin (150 mg) and keep waking up with a sore jaw from clenching (or maybe grinding?) my teeth at night. It used to be something I'd do occasionally from anxiety, but now I seem to be feeling more symptoms of it. I think I'll mention it to my pdoc when I see her Thursday along with some other possible side effects (I've been on the Cymbalta for a few months but just started Wellbutrin 2 weeks ago).
