> I started by drinking almost a liter of milk a day but somewhere along those 2 years I became lactose intolerant. Well this isn't really surprising to me, assuming that you didn't drink raw milk. Processed milk doesn't have the lactase enzyme, so your body has to produce it in order to break down lactose. Consuming that much milk puts your lactase production into overdrive, until it eventually fatigues and you become lactose intolerant. It's rather ironic, that people who are lactose intolerant can actually consume raw milk, because it still contains the lactase enzyme, so your body doesn't have to produce (as much).
