Too much desk time.

It has been an adjustment for me in terms of working in a cubicle. In my prior jobs I either shared a big open office or had my own office. Most of the time I was out on the road so I was never really at my desk anyways. Now that I am sitting at a desk 8 hours a day I find myself really aching by the time bedtime rolls around. I don’t know if I need to adjust my chair or what but all that sitting is killing me. All I want to do by the end of the day is curl up on one of our heated mattress pads and wait for the pain to go away. There isn’t much I can do about the way my desk is organized. I guess my only hope is to wait and see if my body adjust to this sedentary lifestyle over time.
