I think you're too nice! Don't worry about the carb pusher's feelings.

When I was first diagnosed with t2 diabetes, I wasn't very strict - I thought meds would take care of everything. So I would cave as soon as something wonderful smelling/looking/tasting was put in front of me. Learning to say no to others was a piece of cake (sorry!) compared to learning to say no to myself.

Once I was truly converted to taking care of myself first, I never again worried about saying "no" to anyone else. I'm not exactly sure why, but no one argues with me about food.
