Take really quick showers if you feel icky. They work well and don't use much water.
It's an art.... I can take one in 60-75 seconds- suds and rinse only the strategic parts, everything else gets a nice cool rinse off. Very refreshing!
Make sure you have a water economizer on your showerhead if you are into saving even more water. Have a low-volume flush toilet, or put a sealed jug of water in your toilet tank to cut down on the tank volume. Don't flush every little tinkle. Turn off the water while brushing your teeth. :)
