Don't know if it's the lactose, the fat, or something else (hormones, antibiotics, or all the other crap they feed cows) but I am just not able to tolerate milk anymore. Tried a single glass yesterday and it's taking revenge on me this morning.
This should go on the pissed-off thread, I love the taste of milk, drank a gallon a week when I was teen, stopped in college because I couldn't afford it, haven't been able to tolerate it since then. I have not tried a lactose enzyme - which I think would be my next step. I can eat cheese all day - except for full fat stuff like Brie which will wreck me if I have more than a little.
