Susan, I'm very sure that exercise won't help the palate. I'm usually affected when I've done too much. I have to get a good night sleep to get some relief. Is the weakness all day or more prevalent in the evening?

Annie, I find myself clenching my jaws at night while sleeping and have tried to relax my jaw during the day, I catch myself sometimes during the day clenching, but relax my jaw as soon as I'm aware. I'm not sure if the clenching is MG related. I was told it's Bruxism. If I gently keep my teeth together, my teeth chatter. So, why does my palate and bulbar muscles get weak at night instead of morning?
