Some suggestions -
1. No baths on weekends

(I know, couldnt resist though)
2. Eat more salads, more healthy and makes you feel less thirsty
3. Brush with the faucet closed
4. Grow a beard!!
5. Bath using a bucket! Or just head off to the beach instead!!
6. Keep your surroundings neat and tidy (lesser amount of jhadu and pochha required)
