Nah...that wouldn't be low carb!

Allen...with all the stress you have been through the past few weeks, I'm surprised that it didn't happen sooner.
It's interesting that you said that it wasn't a craving, but an irresistible urge to eat carbs. Allen...that's a craving!
Anyway...what's done is done and it seems that you came away from it with some newfound knowledge...carbs don't taste good to you anymore! The next time that you get the urge to go off on a binge, stop and remember how not worth it all it was last time. Remind yourself that it didn't taste as great as you thought it would and then go get yourself a big steak or some lobster (or whatever protein dish you think is the best tasting) instead.
Above all, don't beat yourself up. Pick yourself up and move on with the lessons that you have learned today.
