So it has been few days now, still liking it. In fact I have to say it was physically more difficult making the transition from sitting to standing than was the transition from standing to treadmill.My top speed thus far: .7 MPH - speed the Mayo recommends, and I understand why now. The default start speed was .5 MPH for my machine and I tried to go that speed but found it was just to slow. I keep walking into my keyboard support shelf. .7 is a more natural speed. I do not really have to think at all about walking, it becomes very natural.

I did some adjusting to the shelf unit supporting my keyboard and mouse. The extra shelf did stabilize my keyboard. I also raised the shelf supporting my keyboard so my arms bend at right angles at the elbow. Previously my shelf was to low and I had bend my wrists to type, which hurt after awhile. I also found I nice padded wrist support unit for my keyboard and mouse. It looks early 90s hand made computer retro but it works great.

Since my Treadmill is up against the wall it is very difficult to turn off the power when I leave. I had crawl under the shelf and feel around for the power switch. I have since moved the treadmill plug-in to a power cord that I can switch on and off with ease.

I am usually on 1-2 hours then off for an hour or two then on again. Usually stop altogether by 3:30pm or 4:00pm as by then I am tired. I expect that to change as I get more use to it.

What is somewhat surprising is when I just stood at my desk, I would have more discomfort than walking. Moving around appears to help. While sitting in a chair has some obvious comforts the long term problems I experienced (not including weight gain) are now gone.
