About eight times a week, maybe nine. Some days I'll shower in the morning, then before bed so I'm clean-ish in the morning, so I only need a shower by about mid-afternoon the next day to go out that night. Lather, rinse, repeat, if you'll pardon the pun.
Every two days. I got some shit in the mail saying my water usage is too high or something and I'll get charged more if I keep it up.
So I sacrifice being clean so I can wash my driveway everyday and water the stupid astroturf my parents have in the backyard. Oh and I also cut down on using tap water to make Kool Aid
