Meg, I agree with Lucy - as hard as it is, just try to go with it. Emma seemed to have day and night completely back to front at 3 weeks. She slept beautifully through the day then was up every hour or 2 through the night. People gave me all sorts of advice, some of which I tried, but nothing worked, so I just went with it. Before long she had worked out night and day for herself and is now a fantastic night sleeper (at only 11 weeks she has slept right through twice \/ ) and it seemed like only the other day I was asking what you are asking. I was really glad I let Emma work it out for herself, because I didnt want to mess with the sleep she needed - even if it was through the day. I know it's hard, but it will get better before you know it!
