Re: Yogurt help (and others)
I usually eat at least 8 ounces of yogurt daily--- with breakfast daily, sometime during the day and before bed with PB-8 probiotica.
I think taking a digestive enzyme after meals and between meals may help with the belching. It sounds like your system just is not producing enough for proper digestion. I have used digestive enzymes for years--- I never belch after eating even steak, spicey foods or what ever.
You may want to Read JimmyRay's post about enzymes on the Digestive Disorders board.
I've never had the voice/cracking problem you talk about and do have GERD but rearly ----it's not an every day thing. I use homeopathic remedies for the inflamation/burning whenI need them. As you know------you don't want to get Barrett's Syd.---it leads to cancer.
