Oh, notALICE, coffee is notorious for digestive problems! It's the caffeine; I can't eat
or drink anything with caffeine in it. You may be sensitive to it, too. Some bipolar
people are. I know it could be hard to give up, but could you begin by mixing some
decaffeinated coffee with regular coffee and reduce the level of caffeine? Then if
it works keep reducing the caffeine until you are drinking 100% decaffeinated coffee.

It makes a big, big difference in how we feel. Your idea that it may be a bunch of
new things may be right on target. All medications are acid in digestion, and coffee
is listed as one of the most acid things we can drink.

Drink lots of purified or alkaline water if you want to help stop it. (I would suggest distilled
water, but it's also very acid in digestion.) I would go for those two things: removing caffeine and drinking only water rather than adding another product to your schedule of medications, particularly over-the-counter products. (All milk products are high acid-forming in digestion, by the way.)

Check the internet to see which foods are high in methane gas by-products. That may ring a bell for you in your diet.

Take care.
