Budget

I'm doing up a budget. Well, at least I'm attempting to track our spending for a month or so to see where our money actually goes. Aside from into Puddleduck's tutu collection. It's such a depressing thought I can barely bring myself to do it. I figure some cool software might just help me over the line and towards cold hard figures onto a spreadsheet. Does anyone have any recommendations?

Or should I just keep my head in the sand and ensure I can keep sleeping well at night?
