I don’t take my chances. Maybe you’re sleeping because it sometimes takes hours for a reaction.

Maybe it is not the milk but rather something you add to the milk....or the type of milk?

My doctor has no answer for this as well.

I have honestly never heard of or experienced this!

Thanks for your responses. It is not just milk, but cheeses, ice cream, etc. and other dairy products. I find that Lactaid helps me lead a normal life with dairy products. They come in tablets and chewables that you take before eating dairy and I recently found that it even helps when I take the Lactaid during and sometimes after eating dairy only because I forgot to take it before. Some restaurants put milk products into scrambled eggs. Now I have my Lactaid to take with me when traveling or going out for breakfast or want cream cheese or ice cream..
