@fify-- What you heard is true, goat milk has less lactose than other types of milk and most people who are lactose intolerant can have it without issues.
I'm kind of surprised that you can't tolerate cottage cheese because cottage cheese is very low in lactose like the article said, because of how it is made. I wonder if the product you tried was not up to par. You should give another cottage cheese a try, preferably an organic one and see how it goes.
You can always switch to goat milk products. Goat milk and cheese have a distinct taste that takes some time to get used to, but they're very healthy and safe for those with lactose issues.
