Don't re-read your work immediately. Just write. Keep yourself on track with your outline (you have an outline of some kind, right? Even if you're a pantser, you have some idea of where the story is going) and don't look over what you did for however long you need to lose familiarity with it. If you need two weeks, then write for two weeks and don't look at anything you've written until 14 days have passed. In fact, you could even try starting each day with a fresh document and not allowing yourself to look at anything less than 14 days old (date each document). You don't want to stop writing, but you can stop re-reading. Or as SF. notes, try working on two things at once.
