Besides TP, living for extended periods of time on unsupported trips, means taking very good care of your body. You must be as clean and well lubricated as possible. You cannot afford to get sick, carry vitamins including C. Carry a towel. You will want to leave every thing behind except what makes you feel good (like maybe down socks). I like "no rinse" body bath, but I hate their shampoo and cream rinse. I can take a bath in 6 ounces of hot water and a splash of no rinse and it really does cut the smell and makes me feel clean and afterwards I am willing to get into a clean sleeping bag with myself.
Of course everything eventually runs out. Then you come home.

I think if you practiced at home, jump from the toilet into the shower? Anyway I would certainly practice before committing to it. Just My $.02
