One other thing that has helped me keep my sanity: wash and fold laundry service. You take your dirty laundry, put it in a bag, and they'll clean and fold it for a modest fee (the place around the corner from me is around $1.10 a pound). In urban areas you can find services that will pickup and deliver.

It's a luxury, but it isn't that expensive (especially if you typically rely on coin-op laundromats anyway) and it's one less thing to worry about.
