Thanks for sharing ur experience. ..I was little worried.. hope it goes off early... :)
I also experienced excess salvia starting around the same time as you. Unfortunately for me I continued to experience it part way into the second trimester, and occasionally still do currently in the third. Good news is, is that it will go away at some point! I read that the excess salvia is your body's way of keeping germs out of your body, so it's not necessarily a bad thing, annoying as it is :)
