Works for me during summer and if I go into the office early. Doesn't work during winter (thought of getting up in the cold is a strong deterrence) and doesn't work if I don't go into the office (the kids hear me and decide to get up early). At night, I have no distractions and if it's cold I'm already rugged up.
