How would you split your time browsing your favortie sites!

For me sometimes i spend more than 10 hours per day but i am trying to control these days as my exam is near and not only that it really hurts my eye. Apart from that time management is not organised, it depends on my mood for spending the time on a site. But most of my time spend is on mIRC playing trivia. Hope people her also play trivia games, i really like it and i spend most of the time playing those trivia on mIRC and the remaining hours on mylot.
