My symptoms also seem to temporarily worsen when upset/stressed.. but recover as soon as I have a rest period. Like anacrusis said, when I have adrenaline going it helps temporarily, but I do crash..
Abby- i find myself doing just that.. very tense and I don't even realize it..especially with my jaw!!! Then I can't keep my mouth shut for a while - i'm sure I look lovely with my mouth wide open

My jaw will kind of vibrate with weakness if i try to keep it shut
