Question about powder shakes for pre-op

Has anyone used or does anyone know if its okay to use Herbal Life shake powder for the pre-op diet. I 'm getting banded on 9/19/08, per the MD instruction I just need to fast a day before (just clear liquids), but I asked one of the nurses if i need to do anything else, she said to drink two protein shakes and a sensible lunch/dinner the week prior...that means I have to start on Friday! I'm just not sure of what shake to use..I have a whole container of shake (cookies n cream..yummie) that I had bought from Herbal Life...would that be okay to take???? thanks

If they are low carb, sugar free, and fairly high in protein (17 g or more) then yes, I'd say so, especially since they didn't give you a specific one to use.

under 15 grams carbs
