blocking a website and all websites that share that domain

[Lilivati]

Hello,

I've been having a bit of a problem at school, namely, my work is
boring and I've taken to surfing a web forum instead of actual work.
It's at the point where I have a great deal of difficulty stopping
myself from doing this- some mix of habit and addiction. (Sad, I know,
but there it is. I go to look at the forum automatically and before I
even realize what's happening I'm sucked in.)

It occurred to me that if I could block the primary site and its
subsites it might help break the cycle. Is there any simple way to do
this?

For example a site www.blah.com, with its subsites being
www.blah.com/board1 etc. There are a lot of subsites so blocking them
individually is undesireable.

My school does not provide computers, so the machine is my own and I
can access whatever files are necessary.

Suggestions are appreciated.

While there are technical solutions, none of them are going to work as
long as you control the PC.

This is where you either grow-up or you get in trouble.
