I commuted today and I have to get up earlier than normal. The first day was hard for me to get up, but this morning, the thought of biking got me out of bed on time. Although my girlfriend was still in our warm bed peacefully sleeping, which was hard for me as it is still kind of cold in the mornings here.
Coffee did help as I fired the Mr. Coffee up as soon as I stepped out of my room and I feel better and more alert in the morning.
