I'm scheduled for my sleeve on July 11 and am on day 9 pre-op diet. I have to agree with your revelation. A couple of days in I was like "Hey, this isn't so bad, I'm down a couple of pounds, the shakes are decent, I can eat a salad and chicken/fish for dinner. Why don't I call the doctor and cancel and do this for a few months". Why? Because last night I would have killed someone for a slice of pizza. But it wouldn't have been one slice, it would have been a whole pie, probably followed by ice cream as I would have said to myself: "well you messed up so go big or go home".
I'll be keeping my Tuesday appointment with the surgeon!!!
