I was born with asthma. As a child into teen, I was able to eat ice cream, yogurt, and drink milk. It was when I hit 19 and my early 20's , when I started getting extreme chest congestion after I ate or drank anything dairy. I can still eat cheese, but I cam no longer eat ice cream or drink milk. Can you tell me if it would make since to try either skim milk or 1%?. I recently tried Soy, but that made me congested as well.
