I love kefir!

Actually I drink the Lifeway low-fat and not the homemade kind the Chersky and Turks have made for centuries. I have Irritable Bowel Syndrome and reflux disease and it helps me with that more than any pills. I sound like some kind of miracle cure commercial but for me it must calm my insides. One of my grandpas like to drink sour milk for his stomach issues -- this was raw milk from his dairy farm, not homogenized and pasteurized.
I was drinking it in '85 (dunno the brand, I saw it in a health food store) because with working and going to college, I didn't always have time to eat right or else sometimes my stomach was being a pain in the butt so I drank that to put something on my stomach.
