i've been using my standing desk setup for 2 weeks. it's amazing. all of the energy that used to go into shaking legs and fidgeting and not focussing is now gone. i'm a little more tired at the end of the day (probably a good thing), and my knees, ankles and feet are sore at the end of the day as well. i'm not positive that's going to go away, but it makes sense that it would, and everything i've read confirms that.<p>my back doesn't hurt from sitting anymore and my arms and wrists are in much better ergonomic positions as well (i used to do some ergo design as a manufacturing engineer).<p>i think there are tremendous psychological and physiological benefits. i'm more focussed, i'm more satisfied, and i feel like i'm getting more done (obviously all subjective). i haven't found my attention drifting at all in the last few weeks, and have not once thought to myself, "damnit, just get back to work." if i get distracted, or need to think about something, i just walk around a little. i'm not stuck in a chair-jail. i also keep a soccer ball nearby, and find i'm often dancing a little when music is on. wonderful.<p>just got an ergo mat to go under my feet. should make a big difference as well. i'm still not done setting it up. i've been stacking boxes at different heights to test locations for the keyboard and mouse. i'm close.<p>once you take your desk apart and setup a standing desk, you are forced to use it. this is much different than an exercise ball which you can easily ditch for your chair-jail.
