Is there anyone out there who knows how to forget certain things?

Hiya

I've been trying to forget some URLs (or links) to certain time-wasting websites, but the harder I try the better I remember them. I have already done the obvious, like wiping them off my bookmarks, toolbars, bookmark history and any other place that might have stored them. I have also stayed away from my computer for several days, hoping that that might wipe my mental 'hard-disk'. But no luck!

It's a bit like when I was younger and tried to break a serious chocolate addiction: I had to literally force myself to take a different route across the supermarket so that I didn't end up at the checkout nearest to the sweetie displays with all the chocolate.

Any suggestions are more than welcome!
