Well darn Christi..........sorry I didn't see your post earlier.
I wouldn't worry about those tiny nibbles of biscuit a bit. You caught yourself and stopped at the nibbles.
Some people would have said "Well, I already had a nibble, may as well eat the whole thing and start over tomorrow". You didn't do this, you immediately said "What the heck am I doing?", and controlled the moment.
It is very hard not to eat forbidden foods at Cracker Barrel. We don't have them on the west coast, but having lived in the east for most of my life, I am very familiar with them. Breakfast at Cracker Barrel is to die for. Good thing you weren't having breakfast there.............just gotta have the biscuits and gravy........mmmmmmmmmmm.
Anyhow, you are fine........forget about it.
