I try to avoid a lot of dairy, a small amount in my tea is OK, but I use soya milk at home. My main reason is for a gut disorder which has never been properly diagnosed. By process of elimination of coeliac, Crohn's, etc, I was told I had IBS (surprise surprise). Also, I had gallstones at a ridiculously young 30yrs, wasn't overweight and was vegetarian, consuming very little dairy. Anyway, the docs never even looked at dairy or foods other than gluten, but I'm positive I don't tolerate dairy well. I had a milky cappuccino last week and, 15 minutes later, needed a bathroom urgently. Like others have said, my obvious food issues just make me seem even weirder and I'm sure some think I'm a hypochondriac or attention seeker.
