ADDICTED- Diet Dr. Pepper

I've been doing pretty well on the diet front these past few days. (Yay me!) Today's weigh in had me down 1 pound, putting me back at 167. It would have been nice to finally be past 167, but at least I lost the weight I had put on during my diet funk.
Brittany does in fact have her groove back...

With one small exception....

This week, I've been having a full on love affair with the Doctor.
Diet Dr. Pepper that is...
I know, it's bad. It's unhealthy, and it's a forbidden love.
But what can I say?
"I'm A Pepper"I always have been...
It's just so darn good!

But this seriously has to stop.
I've had more diet Dr. Pepper this week then I'd like to admit.

I need an intervention.

Any words of advice?
Do you have a guilty diet pleasure?
