I usually get up around 1 p.m., work until 4, go to the pub, eat dinner and hang out with the wife until 8 or so, then work until about 4:30 a.m.
So just under 12 hours a day, 6 days a week. On the day I decide to take off I usually work about 5 hours. I used to work much harder on less sleep but I guess I'm getting older

I like it though, I doubt I could handle a real job anymore, I never did like bosses much.
