Texas WLS Shakes

Has anyone had them? How much do you use on the sample packs and with how muchwater. It says 1/4 cup, 1 scoop,(what is the scoop measurent) How much ice do you use? HHHEEEELPPP!!!! I purchaesd the sample starter pack. It looked great and I received a lot of litle extra's as well. I am 6 days post op as well. I have some drainage which I an handling well. The previous drain site is higher than the one draining know and that is why. It must come from surgeical irrigants. No s/s of infection thank goodness. No temp either. I feel great.
