I have had heartburn forever and I tried the prescription meds, but I feel the Zantac works the best. But 75 is not enough, make sure
you take 150 mg. twice a day. Also,
you can supplement it with Mylanta or Maalox liquid if it's really bad.
I'm not saying this will be a miracle cure, but it's worth a try. Unless you tried Zantac already, I don't know.
Let me know.
