+1 it's like a drug if I go w/o riding I get annoyed by customers and coworkers easier. I also find the days I ride more I need less sleep. I work 2nd shift and go to bed around 2:30a then get up about 8:30a. On days I don't ride I sleep until 10:30a on the following day. I seem to sleep more effectively on the days I ride its really strange, I often wonder if the extra exercise gives me a deeper sleep needing less then. Does anyone else notice the same?
