This is one of the weirder parts of pregnancy: Some women find that in the 1st trimester, they salivate like crazy. It's probably connected to the nausea of morning sickness -- think of how you salivate just before vomiting. There's not much you can do for it other than to wait; it usually disappears by the end of the 1st trimester.
