Allow Urge but Redirect – BBR

The other day I allowed an urge for a muffin but then I ended up still buying something with a little bit of sugar. How do I model this redirect?

My models were:

C At the train station
T I want a muffin
F Desire
A Acknowledge the desire and allow it
R Stick my long term plan

C At the train station
T I allowed my urge for the muffin but now I still want something with a little sugar
F Worthy
A Get trailmix
R Allowed urged but rewarded myself for working so hard
