Not in your group, but from a fellow sufferer due in September... Last week I bought an inexpensive bottle of calcium/magnesium/vit D supplements recommended for my leg cramps, and they've had the very welcome side effect of cutting down on the heartburn (I suspect it's the extra calcium helping). I bought them at Trader Joe's, and they're food-based, so perhaps they're better absorbed than Tums. If I take one right before I go to sleep at night, the heartburn doesn't wake me up, and I feel really good until the following evening (when I pop another one and go to sleep). I've also had no leg cramps in the last week. It could be a placebo effect, but it's working so well for me, and I see no downsides. Good luck, heartburn is my biggest enemy right now!
