I'll have a protein shake, maybe once or twice a week as a post-workout recovery drink. I use whatever is cheap...usually EAS or Optimum Nutrition (either vanilla or chocolate), both of which I can find at my local grocery store. I mix 8oz of skim milk (lactose-free), 1 scoop of the protein powder, a handful of fresh or frozen berries, and 3-4 ice cubes. I blend that up into a nice, thick shake-like drink. It's yummy and very satisfying.
