I can have it sparingly, but honestly for me it's no better than cow's milk. So I might as well do cow's milk. Both are about the same.

Interesting. I can tolerate dairy, as long as I don't do too much of it. (Dairy for me is largely cheese and yogurt, occasional ice cream). I may try your experiment and go off the soy for a while just to see what happens-- I really only use it to put on cereal, or more rarely to make mashed potatoes. I quite love the latter, used to eat plenty of them, but as you know, they're a carb, so... so only occasionally these days.
