I've been on my pre-surgery diet for a month already and have my surgery in 13 days! I drink my Protein supplement shakes 3 times a day, have a lean cuisine for lunch with a 100 cal. greek yogurt and Water. I've been using the Mio flavorings for water instead of my old huge glass of fruit juice in the morning and I'm able to tolerate it pretty well. I have a liquid diet the 2 days prior to surgery, and I have to stop all my blood thinning medications, herbal supplements, and caffeine 10 days prior to the surgery date of 2/4/14! When I get super hungry, I eat a dill pickle or a piece of fruit. I have been told to lose 10 pounds before surgery - and I'm down 8! 2 more to go..... (sigh). I hope we do really well! Good Luck and I'm anxious to hear how it goes with you.
