Hi ladies I am 52 and was scheduled for surgery for 3/12, but cancelled it. I have a lot if fear about being nauseous after surgery. Very fearfull of malnutrition and feeling weak. Please any advice. Very conflicted. My stats are 5"8 and 242 down from 267. I have taken the pr-opp diet very seriously. Am open to all of your advise and need support, as several friends have said not to get it.
