I am having some of these issues myself. It is torture to take a shower. I try to manage it every few days.

Our hot water heater is broken so I am actually at my own limit of uncleanliness. One more day until we have water. I know the solution is to go to the Y or my parents' house, but it is so hard to get into my own shower 50 feet away, forget packing my stuff and getting into the car and driving 20 minutes to get a shower. I'll just wait till the water is back.
