I've spent the past two weeks working on-site at a client where I walk about a half mile each way to/from the office and another half mile to/from dinner, which is a stark change from my normal "get in the car and drive to work" routine. Even this small change (which is paired with eating out and having a few beers each night) has allowed me to sleep less than I normally do, while staying just as alert throughout the day and craving caffeine less than usual. I'll be going back home this weekend and I need to figure out a way to push myself to do some walking even though I'm not forced to. Hopefully my experience these past two weeks will be enough.
