What was the name of this show?

I used to watch this show all the time and I can't remember the name
of it. I'm hoping someone knows it.

It was a game show, and the contestants was usually a couple, and they
would stay up all night long studying for the questions that will be
given on the show. They weren't allowed to sleep at all. After the
time ran out for studying they had to go through I think two rounds.
The first one would always be them on this hamster wheel thing and the
host would question them. The next round would be some matching game
of some sort. I think they won money if they got a lot of points or
something, I don't remember. It used to air late at night, and I
could've sworn the logo in the title was a tired looking eye. I'm
guessing it got cancelled because I haven't seen it in years, and I
didn't think about it till the other day.

Any of this ringing a bell?
