Often the first day of a good new thing is really overwhelming and doesn't feel all that good, at least in my experience. It takes a little while to get your bearings and figure out what the expectations of you are in the strange new place.

I enjoy a nice cup of herbal tea at the office, usually one around 8:30am and another in the afternoon. :)

The handy proximity of your office to the south end of Denver also means it will be easy to meet up with you after work! :D
