I have horrible heart burn, I have had it since 2nd trimester. I get it at least 3 times a day. I eat Tums like candy and I was taking Zantac (prescribed by doctor) but it takes a really long time for it to kick in so I gave up on that and went back to tums. If I am really desperate, I down milk (plain or chocolate). I can't wait for this side effect to go away, it's driving me insane. I would have to say it is my biggest complaint because it happens every day, multiple times a day.
