It used to be probably about 2 hours before I had to get up. Since I'm freelance now and don't have a real schedule, you'd think I'd be able to stay up as late as I wanted, but nooo. The dogs wake my ass up around 7 am no matter what. Lately I've been staying up until about 2-3ish playing Persona, so I usually end up taking a nice midafternoon nap.
