A day late in posting
Drank another gallon of whole milk today - my stomach seems to be doing fine with 3 large drinking sessions instead of glasses throughout the day like I did before.
I ate some tomatoes, a bit of hummus, a few slices of pizza, a few apples and snacked on some almonds. I also had 4 cups of weak coffee in the morning and a double expresso at night. I've been drinking a lot more caffeine lately, probably cause it's nice to drink something hot in the cold.
Obviously the milk is good, but it's only about 2000kcal and I don't want a mono-diet so I need to make more of an effort to work in lots of other food.
