I lived on mylanta and zantac (and lots of milk, but I saw you're not on dairy).

I also was prescribed Periet which actually makes you produce less acid, I gather - worked well during my first pregnancy, but when I asked for it during my second, they said it wasn't given to preggo eggos.

Maybe ask your Dr, because it was the ob who gave it to me the first time!

But over all, sadly, it was all just managing symptoms. Heartburn knicked off week 34 with DS1, and after the c/section with DS2.

Hope yours leaves faster!!
