I only drink skim now, with the occassional chocolate (which I guess is more like whole milk). When I was younger I thought skim was gross, but now I absolutely love it. Fat in milk to me is just wasted fat intake, drink it for the calcium and modest amount of protein, which skim has in similar amounts to the other variations.
That Silk soymilk, esp. chocolate is delicious but its sooo expensive, I just stick with the store brand skims which are still like $2.60 a gallon.
