I do, sort of. I tried a makeshift standing desk and the most significant comfort issue was definitely feet, though standing on a pillow and walking around occasionally helped. I suppose body size and type makes a difference.
Ultimately I think what made me go back to a sitting desk was (unrelated) lack of sleep. Even when I could handle using a standing desk after being paged at 2:00 AM, the next day I'd be exhausted and lack the necessary willpower to keep using it. I'd wind up opting for propping myself up on the bed with the laptop, which is a horrible alternative.
