I'm having better luck with pre-op diet, so long as I not at a social event. In the first 10 days, I dropped 10lbs despite going to a stag in NYC. Then this week, I was in a wedding party, so a few treats and beverages were had.
I actually have no problem sticking to the diet (shake for dinner, small salad from salad bar (no dressing), and a shake for dinner), so long as I am not being social.
I've had to cancel or decline lunch offers (even the free lunch) variety, as I it would be a challenge to stick to my guns. Also, as I haven't told my friends yet, it seems odd when I am eating nothing but salads***. So it looks like if I just lock myself in my office or my condo, I'll be fine.
I don't have the problem of casing my apartment for food (unless I wanted dried pasta or oregano). My bigger issue is that so much of my social life revolves around food - wine and cheese, steak dinners, weekend brunches.
*** I plan to tell my friends, but not until the surgery is complete.
