I find that creating a schedule for myself helps where I force myself to work on something - even if it is menial things that still need to get done for the site.
I also disable all chat/instant messenger clients since you always lose productivity when switching from one to the other.
The other thing that you can do is try working from a different environment - if you find that you are browsing too much at your desk, try moving somewhere else that you can consider a "work only zone."
As a final step, try disabling your router for a bit and only give yourself access when you achieve your self imposed deadlines.
