Friend of mine has the same issue as you:
He's restricted to playing games only at weekends; but -ironically- he plays all day long then.
I'm not shitting you: he'll start at 06:00 then play 'till 04:00 next morning.
So well... It's a bit of a stupid "punishment" in my most humble opinion, but make of it whatever you like.
Or a precaution? Meh, anyway, we men will always find distraction as long as studying is involved ;]
Awg : STFU stupid bitch.
@Librarian : Yeah im just posting this here because he never done it before.
