Caffeine

It is very interesting that while on vacation certain coffee addicts arise from the dead to be the first to the coffee pot in the morning. Is it getting the first fresh cup before everyone else so exhilarating? What causes such addiction? I do have to say,it is nice that Dave is not here this trip with his super 8 coffee mug hogging the first pot of the day. The simple aroma of coffee is very uplifting.
