Darthvadar: I've read some of your old posts; you took excellent care of your mum, she definitely was in good hands and in good company. You're a pro!
When I was reduced to taking sponge baths (not for long because I found the peel and wraps), I found a hair cutting place that would wash my hair for $10.00. It was a bit expensive, but it did give me that feeling of being thoroughly clean. I always felt so much better in spirits afterwards. Keep in mind that this is only temporary. Hang in there!
