Michelle - I'm in the same boat. Though I didn't suffer before getting pg, it has been bad for me since day one and still is.
My Dr. told me to take Tums, up to 10 a day. She never mentioned anything about stones to me - but I have read that as well. I guess I just assumed her "10" was in the safe range. I'm not eating that many a day anyway. I take 2 at a time, maybe 6 a day at the most.
Nothing I eat or don't eat helps it. You?
