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!
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. :)
Zantac and Mint gum did me great justice!
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
