I did. I was even in a shared cube environment so I couldn't even raise the desk surface. So instead I got some boxes and put a piece of plywood on top, then put my monitor/keyboard/mouse on top of the platform. It looked pretty weird, but after about 3 days two other guys on my floor copied my bit. Now I'm at home so I have a better setup, but I'll never go back to sitting no matter where I work.
