I've done it many times Ryan. Came home from work, started playing, forgot to eat, phone or any other intrusions blocked out, then I would lean my head a little to the left, beyond my monitor, to where the clock is, and see that I have eaten up 5 hours and it is NOW 1:00am in the morning, and I have to get up for work at 7:00pm, and I haven't eaten any dinner, DOH!!!
Sad....
But there you go
