I work as a developer on client projects--my technique currently is to leave myself a small todo list towards the end of work in Simplenote or a github comment. Then I shut the work side of my mind off, enjoy my evening and sleep, wake up, start on TODO list, and if other client needs arise, hop on those and get back to TODO list later. Rinse, repeat. If applicable, my tip is to allow yourself to enjoy the evening without thinking too much about work, so you feel rested and refreshed to tackle the next day.
