I used to drink about half a gallon or more of milk a day, sometimes up to a gallon and a half on weekend days. I found out that dairy is a trigger for my intestinal issues so I cut out milk almost completely. Cheese has to stay, being from Wisconsin and all. I did this a few months ago and have already gone back to my high school wrestling weight, mainly from my stomach and feel better. Additionally the food budget is probably down by at least $50 if not closer to $100 a month.
