Thanks Mr. Boswell,
It sounds like you are definitely dialing in on the right formula for success. Half a sandwich... that sounds like a reasonable amount of food to lose weight on. Curious - are you actually eating bread? I was told that bread was probably not ever going to be possible. In fact, my docs have said try to eat an almost exclusive solid diet of Protein, a little dark veggie (but not too fibrous) and a minute amount of starchy veggie (mashed potato?). Probably very healthy but a little boring I am sure.
Last question - when you feel full, do you feel satisfied? Are you taking a long time to eat?
