Hi maidmarian,
Oh yes I'm a confirmed cheese lover as well and once upon a time I also had a problem with dairy but I found out the problem that I had with dairy was not so much the dairy itself but that it was pasteurized dairy products.
Since having switched entirely to raw dairy as in raw or untreated milk, home made yogurts made from the same milk and nonpasteurized cheeses, that problem was greatly reduced. In addition, I also sorted out my stomach bacteria by taking a good a quality probiotics and also topping out on stomach enzymes again by taking enzymes for the stomach. Neither of those are expensive and once you've repopulated your digestive system with those bacteria and enzymes that it needs, you shouldn't find you have anymore problems. In addition, eating natural live fresh yogurt amongst other healthy probiotic food will help increase the population of those beneficial bacteria and at the same time discourage unhealthy bacteria from living in your intestinal system.
As a footnote to that, raw milk does contain all the enzymes we need to digest it. It's really only the pasteurization and processing procedures that kill those off making it hard to digest for some people. One thing I have noticed from myself is that providing I continue to eat a reasonable proportion of raw dairy foods with all the enzymes in them, the occasional portion of tasty though pasteurized cheese doesn't affect me anymore simply because my digestive tract now contains adequate quantities of the enzymes needed to assimilate lactose, galactose and of course calcium which is one of the reasons why we drink milk in the first place.
So the bottom line is I would suggest you at least try firstly putting your stomach bacteria and enzyme population in order and then once that is done switch to raw milk products for a while just to see how you get on.
Hope that helps,
Mark
