yea i did something of the same thing
i started drinking easily 1/2 gallon of milk a day. still drank water too. i think liquid calories are easier to get down that solid food.
try this: get some natural peanut butter. get a huge glass of milk. take a tablespoon of peanutbutter, and shove it in your mouth. proceed to get a lot of milk in your mouth so that it isnt so sticky. swish around until it becomes a peanutbutter, milk medly/sludge. swallow. repeat as desired
