Lifestyle tips

I get heartburn as well. I have antacid chews that I take when my heartburn gets really bad. Heartburn could be a sign of Gerd, which could be happening if you have sleep apnea. I would bring this up to your doctor, and see if they can help you.

I take a prescription for heart burn, but the over the counter heartburn med, "Zantac" uses the same medication as my prescription meds do.
I'm not sure if it is available where you live.

Try over the counter antacids. Ask the pharmacist and see what they recommend. If that doesn't work, see you doctor. I did and take Lansoprazole tablets every day and a swig of Gaviscon last thing each night. It works for me.
