Protein bars??
I know that I had a different procedure, but one that I found that is awesome and I eat one throughout the day is the Pay-Day protein bar. It tastes just like the candy bar, but with 15g of protein. I start out with it in the morning and take little pieces throughout the day and by the time I leave work I am done with it. It's really good and it's tolerable for me (as long as I spread it out). I can only find them at Wal-Mart though.
i haven't tried these yet, but found them on another post and saved the link:

i do okay w/ the pure protein, if i don't eat more than 1/4. i hate 1/2 once and it was the only time i experienced serious dumping - sweating in the cold and dizzy/naseous.
