WWND?

My WWND diet has spiraled out of control lately – and not in a good way. Those 8 pounds that I lost in January have almost all found their way back to me. I have walked and biked the past four days, so hopefully I can get back on track now. I have yet to achieve that awesome rejuvenated feeling after any type of exertion, though. Many people I know still brag about how exercise is sooo enjoyable and sooo exhilarating. I asked Norm if he is invigorated after his walks, and even he responded yes. I feel like such a freak. What in the world is the secret to obtaining that post-exercise euphoria?
