I have started getting really bad dry mouth at night. I wake up and need to drink a lot. It's not a problem during the day just at night. I'm not sure what causes it. (I'm kind of a hypochondriac and anything out of the normal really makes me anxious) I recently switched over to cymbalta and am wondering if it's maybe a side affect of that. (I take it in the morning but I have heard it releases the medicine slowly in to your body so maybe it takes a bit for effects) any thoughts?
