Phazyme and Gas-X are brand names for a product called simethicone which is a very effective anti-gas treatment. You can find it in the drugstore near the antacids like Maalox. The big chains like RiteAid all have their store brands too which is what I buy because it's cheaper but just as good!
As far as loving beans, tell me about it! My mom's family is from the south and I grew up on bean soup and cornbread or baked beans with molasses!
They don't have to be excluded from Heather's diet, actually they are very healthy. But they sure do cause gas unless you eat them every day and your body adjusts to them, or take Beano. Otherwise it's Gas-X to the rescue!! And a good airfreshener!!
