Sophorosyne,
I also had the "last supper syndrome" for a few days after I decided to do the surgery. Right now I am 3 weeks away from being banded and I feel fine, I am taking time to taste my food and I do not feel hungry anymore. At first I ate more than I usually do and I was choosing high calorie food, which I normally avoid. So my issue because not only portion sizes but quality of food. I probably ate about 6 homemade cookies a day for 4 days, then I felt guilty.
Try to concentrate your energy on calming yourself down for the surgery, if you decide to do it, enjoy the flavors of food instead of stuffing yourself with it. I feel so much better after I decided to take care of myself....
My IBM is now 33. I want to be 22.
Good luck
