E.T.
I had the same thing with both of my pregnancies. Tums helped some, but even water had a bad effect on me. Talk to your doctor about a prescription. There are things that are safe to take that can help. There is an old wives' tale that if you have severe "heartburn" when you are pregnant you will have a baby with lots of hair. It was true for both of my babies. I recently heard that is the only wives' tale that has been proven true.
