Bad for me! Lactose intolerance sucks :(
Oat milk is another alternative I’d recommend. It isn’t a substitute per se, you are going to notice a difference, but it has similar mouth feel, tastes good, and I’ve used it in all the same places as milk (cereal, cookies, hot chocolate) and been pleased with the result.
There was a time the lactose-free choices in the US were very low, I love seeing major brands now carrying lactose-free products. Especially Breyer's ice cream, that was an eye-opener.
Lactase drops makes it simple to convert milk and cream cheese to being lactose free at home.
Green Valley has butter, cheddar and mozzarella! We've tried making lactose free mozzarella before at home, but it was always a disaster.
Breyers has lactose free ice cream.
Organic Valley makes most of it's dairy products in a lactose free variety.
