I'm lactose intolerant. It's not that bad for me... I just get cramps, and most of the time I can handle them. Sometimes its really bad, especially after I eat ice cream. Also, I get really gassy and it's painful. But other than that, I usually stay away from dairy products. I like soymilk and soy slices (soy's answer to cheese). Its not a replacment for milk or cheese, but its decent. I usually eat sorbet or sherbert instead of ice cream. I'm not sure if this is related to my LI, but I also cant drink orange juice or eat anything with a lot of acid in it. I get horrible heartburn. Anything with a lot of tomatoes, onions, hot sauce, and even things that are slightly spicy, will give me heartburn so bad that it keeps me up at night. It gets annoying, but I usually just stay away from those foods. It's really annoying going to a family member's house and not being able to eat anything...
