Not Digesting Milk Properly

One of the recent posts was talking about urine color and it was brought up that obviously whiter colored urine would be a bad sign. I'm somebody who drinks a lot of raw milk as I'm trying to put on weight. I drink it with raw honey because I notice I don't get stomach issues when I have honey with the milk. My urine color when I drink a lot of milk is basically white, the color of milk, which I'm assuming indicates that I'm not digesting the milk properly. I'm not sure if I've ever been able to digest foods very well, as obviously it's hard for me to put on weight and you need good digestion to actually absorb nutrients and put on weight.

What do you guys suggest for digesting milk better besides fermentation/kefir, drinking at room temperature, sipping on it rather than gulping.

Should I do the whole 48 hour egg fast or what?
