Lactose Intolerance

[Cobalt]

I don't have it but I'm interested in those who do. I have a friend who had it so I learned a little about it from her (I don't talk to her anymore though). My thing is I totally LOVE milk/dairy. I love yogurt, milk, ice cream, things with milk in them, etc. What do people substitute milk/dairy products with? Are there certain foods/drinks you can't have that most people don't associate with milk/dairy that does cause you problems?
