Kara, are you on P1? If so, just breathe (well, maybe do that outside?
) and go for a walk, or chew some gum and give yourself a 'non-food' gift...like a hot bath, go shopping for a small new accessory or piece of clothing, or do a hobby you love but never have time for.
If you're on P2, make some SBD friendly bread of your own! Whenever I bake for others, I always make sure to bake for me, too...that way I'm never tempted. I make SBD-friendly brownies when I make regular ones, SBD cookies for me when making cookies for others, etc. It helps a LOT. I freeze most of them so I'm not tempted to overeat (though it does happen...
).
Good luck!
Next time, make him bake at his friend's house!
