I had heartburn bad with my daughter.. I would drink water and I would get it.
Rolaids were my bestfriend. There like tums but they don't have such a chalky taste
Zantac and Mint gum did me great justice!
Take some TUM TUM TUM TUM TUMS anticid®, for heartburn relief. Always work for me. Hate the chalky taste but they seem to work, so I look past that. If that does not work, try Pepcid, Gaviscon, Prilosec OTC, Omeprazole, Pepto, Zegerid OTC, Equate Acid Relief or Alka-Seltzer. If you do not want to go to the store, try a quick remedy-- baking soda or cold milk. And also, you can use PregEase. It treats morning sickness and heartburn. It is clinically proven a safe choice with natural ingredients, so you do not have to worry about anything harming the little one. :)
Apple cider vinegar! About a teaspoon mixed with 8 oz of water, I drink with a straw to protect teeth. It's nasty and the first5 minutes seem counterproductive but that's the only thing that got me through my pregnancy!
