Control yourself. If you cant even get some self control over visiting a website...your in for a bunch of problems in your life. Block the website from your computer, set a timer where your only allowed a certain amount of time on the site, etc. You have got to learn some self controll.
I am obsessed with FunAdvice and I am not planning on doing anything about it :) <3 <3 <3
On a serious note, if you feel it is getting out of hand then just remove it from your favorites and stay off the computer for a while.
block it for a short time...
what site is it? :p
Try to replace it with something else.
