You have a good poing. I did do without these things for almost a year with little problem--and no one loved taters and bread more than I. But having a sandwich (Nature's Own, 5 impacting g's of carbs) does add to a sense of "normalcy." Something to hold your devilled ham...
Nabisco's Snackwell's Sugar Free Shortbread is mighty nice to have with some hot tea.
Variety keeps me on track--and I'm happy to find a few treats now at the grocery store.
Breyer's sugar-free, but blessedly high-fat, ice cream...chocolate...
Russell Stover's sugar free chocolates are pretty good too. My favorites are the Pecan Delight and the toffee squares.
