Right after I posted this note, I read that fennel tea can sometimes help....but you have to drink it every day, to avoid the bloating. You could try that. Just buy a jar of fennel seed at the grocery store, and put about a tablespoon in hot water, let it steep, then strain it. It's worth a try.
about 4 years ago, when my bloating was at it's absolute worst, I think it lasted about 7 months. I had to sleep in a chair, and could never lie down. It was awful. I tried peppermint tablets, which sometimes worked, Gas X, and some others, but nothing seemed to work consistently.
I started thinking it had something to do with female hormones. I'm finally almost through with going through menopause, but it's sure been a rough ride. I would notice, during perimenopause, that around my periods, I would tend to have LOTS more GI problems. Can you relate your bloating to your cycle?
Perhaps some digestive enzymes might help??
And as Dr. Norm has mentioned on the GERD forum, he believes that too many carbs can cause a ton of gas. According to some of his research, if we eat too many carbs, our systems can't absorb them, and they sit there and ferment....which causes alot of gas.
