I had bad heartburn with my first i would drink a tall glass of milk and keep tums near by
If it get real bad even after tums, i would get meds from your dr. I have to do that and take tums.
I read that you should drink water before and after a meal instead during.
Well i was drinking chocolate milk and that was making it worse. As well as trying to eat anything. But i found that sprite helps me.
Zantac is safe to take and works well for me
Tums. Also avoiding the foods you know trigger it like spaghetti sauce which is super acidic.
