Putting Ourselves on a Budget

Now that I'm not working, my husband and I decided that we need to be on a budget. We've been saying it for the past two months, so it's time that we sit down and figure out how we can do this.

I'm already getting better - I use coupons, I go to the library instead of the bookstore, and we hardly ever order food. But there have to be more ways that we can save money. If only my husband would stop taking cabs everywhere he goes...that would save us a lot. But he's stubborn about that - so that's an ongoing battle. Any suggestions on how else we can budget or save money?
