I havent had it until just this last week - but more reflux than heartburn - always at night,(every night) and it kills! Mylanta is fine as long as you dont exceed recommended dosage, and Ive also heard that Zantac is fine and has helped a few of my belly buddy friends! Also try avoiding citrus drinks, caffeine, eating just before bed and try lying propped up on a couple of pillows!! Good luck - I hope you find something that works for you!
