I haven't been using them because really, I don't tolerate milk well at all and couldn't easily get raw milk due to the Food Nazis here. Not worth getting into a herd share program just to find out that I don't really tolerate raw milk that well either.
I do eat raw milk cheese as a rule and I seem to tolerate smaller quantities pretty well. Last night I had Roquefort, the real thing, which is of course moldy sheep's raw milk cheese, and it is delicious and I do okay with that so long as it isn't too much. I also love goat's and cow's milk raw cheeses but tolerate cow's a little bit less well.
