I have always had a milk sensitivity, but would just throw caution to the wind on pizza night. A year ago, I gave up pizza and switched to soy yogurt (I have been on lactose free milk already).
I rarely eat cheese as well.
Yesterday, I had to have frozen yogurt...there was no cramping, it just went right through me (so to speak). The rest of the day was the same way no matter what I ate.
Did I learn? For awhile.
I eat little in the way of raw fruit. And granola, which I love , a small portion for breakfast once in awhile.
What I have learned, is that my body changes. A year ago the pizza was fine, the yogurt was tolerable. Now forget about it.
And we are all different.
