Every day you must write something. A paragraph, a figure, but a something.
If you have figures work out how you want them formatted and so on NOW - because mindless figure reformatting is a much more useful form of procrastination than shiny things.
Same for bibliographies and so on.

Make a committment to give someone a certain amount by a certain time - I'm happy to proof read and nag for you!

I had to resort to writing my thesis in a food court at a shopping centre - there were lots of distractions, but none of them were interesting for any length of time, so writing actually happened.

Delete all icons for solitaire games and other wrascally things. Delete/hide any non-academic bookmarks.

Good luck!
