for programming work I would say 20-25 hours a week on complicated things, and an extra 5 - 10 hours on simple things.
The complicated things are stressing and you need to relax a bit afterwards, and then you can take easy stuff, like maybe an evaluation of what one might do to speed up some process without actually writing the code, just a report. Or simple fixing of design issues, code cleanup stuff like that.
