2 days ago I got a very high feaver.. the next morning I woke up and felt fine... so, I didn`t go to the gym thinking that I`m might caught a cold or something ... so, before I going to sleep I had a glass of milk (without proteins) and suddenly started feeling sick again.....
I think milk is good. I need to supplement with lactase enzyme (Lactaid, etc.) when I drink it otherwise I feel bloated and kinda generally crappy. I only started having this problem digesting milk over the last year or so - I guess it's an age thing. Try it - there are many brands out there at your local drug or gorcery store and they really do work.
Some people are allergic to milk. Go to your Dr. and find out if you are. I personally drink about a half a gallon a day, so its different for every one.
