Novelist Cory Doctorow wrote a great article about how to deal with distractions (family, internet, research) when writing. It's full of great ideas that are both practical and do-able.
Cory talks about keeping a short (20 min) regular work schedule; leaving a 'rough edge'; suggests that you don't research when you should be writing (and includes a great idea for replacing 'the facts' with a marker in your text that's easy to find and replace later); advises not to be 'ceremonious'; not to use a word processor and to to turn off your real-time communication tools (emails, instant messaging etc) during your writing time.
Well worth a read!
