I've never had heartburn before. I bought Tums with my last pregnancy but never used them. Last night about 2:00am I wake up with the worst feeling I have ever felt in my chest. I'm trying to be quiet looking for the Tums trying not to wake my almost 12 month old. Finally found the Tums ate 2 as fast as I could. Felt a little bit better but it just kept coming back. Anything else help you ladies? Cause I have a feeling it's not the last time I'll feel this.
