Sometimes it helps me to think about all the pre op testing that we had to go through. I was thinking about this just yesterday. I had back surgery 2 years ago and I wasn't screened as carefully back then as I was for this surgery. I mean they have tested me for everything, I have had a sleep study, scope, chest x-ray, blood work, stress test, and EKG, so they have made sure that we are fit for surgery. And of course there is always putting our faith in the hands of something greater. Everything happens for a reason, and we've been given this opportunity to do something with it. What sort of liquids will you be allowed on your pre op diet? I have 4 diabetic Boosts or Glucerna per day. Up to 1200 cal, 60-80 gm Protein, and 100-130 gm of carbohydrates I am allowed broth, fat free yogurt, Jello and pudding and popsicles to make up to the 1200 cal. It's not too bad, I like to blend them with skim milk makes them taste more like chocolate milkshakes mmmmm.
