Yes maam', thats my worst symptom. The cal/mag is good, you might try taking some acidophillus too, that helped me. I know what you mean about the belching, shoot I get up and the first thing I do is belch!!! (And toot all the way to the bathroom, hehehehe) And the pain is the worst!! When this all started for me I was sure I was having a heart attack!! I have found in my case that zantac taken before a spicy or greasy meal sometimes helps....I've been on prilosec on and off but I try not to take too much of that as it seems to magnify my tummy troubles, I think it has to do with the fact that the acid is limited when you take them, and we need acid to digest our food properly. But thats just me. And along with the fact that genetically I carry weight in my tummy, peri has made that worse and with the gas....oooooohhhhhh mama, I look prego here too!!! lol Bring on the yoga pants and loose t-shirts!!! I feel for ya gal, wish I could be more help :)
