We haven't had to cut back too much because we are already fairly conservative in our spending habits. I work from home and my husband has a three-minute commute. We really don't fill up our gas tanks very often unless I need to go out of town for a meeting. Even then, most of my travel costs are reimbursed.
Neither of us eats red meat or smokes. I don't own a cell phone. We probably spend more than the average household on beer and wine, but we make up for it by being frugal in other areas.
I've been trying to be more careful about what we purchase at the grocery store -- i.e., avoid buying more than we need, or buying stuff that's likely to go bad before we use it.
I suspect we're eating out a lot less than we used to... On the other hand, that could be because I've been out of town for work a lot lately...
