I feel like throwing up just by thinking of doing that
It's not that bad. How you do it depends on your surroundings. When I was doing a gallon a day, I worked at the Health Food Center and just stored the gallon in the sports nutrition cooler. I'd sip on it for 7-9 hours depending on how long my shift was. However, I think I loved the gallon of keifer a day over the gallon of milk a day. Albeit, you ahve to be a bit more picky when you're paying for the stuff rather than when you're getting it for free.
