Whoa, I'd love to try this if I can find the time. I'm also lactose-intolerant, but it's so common here everything is available totally lactose-free as well. The only problem is those products are much more expensive, like three times normal milk products...and I drink a lot of milk, as do the boys. BUT it's getting to be pretty much the norm that in cafeterias etc. the milk used is lactose-free and also cakes etc. are made only of lactose-free cream etc.

I suppose lactose-intolerance or at least slight version are very common here, I understand something like 20 percent or more of people have at least some degree of lactose-intolerance, and there's a whole lot of people who have a slight case of it and don't even realize it ever, some suspect up to 50% of people here could have some symptoms.

The funny thing is, I used NOT to be, I drank milk and milk products like crazy, but then I spent 4 months in the USA and when I came back I could no longer drink normal milk.
I think my drinking of normal milk all the time kept up my ability to use lactose from since I was a baby, but the milk in the USA was different and didn't support the bacteria in the intestine required for lactose, and thus I lost the ability. I can have some normal milk, but a full glass or so and I'm in trouble.
