One item that is not that popular in the US but is in many other parts of the world is a bidet. Besides cleanliness, a bidet offers the use of much less toilet paper. You are not wiping away filth, you are only drying the area. Using one of the many portable bidets for sale, or making your own, you can stretch one roll of toilet paper out to a month easily. One model that I have (and that I saw on Doomsday Preppers, to give credit) is the pump up sprayers from the hardware store. You don't need to bend the tip, as the show recommended, but it help. You can use sun-warmed water to clean yourself, then pat dry. To sun-warm, simply wrap the sprayer in black plastic or black duct tape. It will attract the heat of the sun when in a window.
Medication stocking is very important....if you know what to do with them, otherwise, they are extremely dangerous. If you take the wrong antibiotic for an illness, you could in-fact be super-powering that bacteria. But, I do say get a book that describes all of your basic broad-spectrum antibiotics and their uses. You can google them as well, and create your own short-cut book on many facts that you want to keep in one place. Buy large and small bottles of everything. Lg. for home, sm. for bug-out bags. Remember to keep your prescription med supply rotated in your bags as well. I usually tear my bags down twice a year and restock with fresh, and appropriate clothing for those next 6-months. Gatorade and Powerade freeze at a lower temperature than water for us Northern people. Ice doesn't help when walking in a blizzard. Gatorade does.
Add honey to your home and bags as well. Raw honey is the best, but pasteurized if you have a weakened immune system, is safer. Honey does not freeze. It provides energy, though not many nutrients, per say. It will sooth a sore throat, aid in burn and wound healing, but most importantly, helps with a stressful time, because it just tastes so good. Add it to plain crackers, and you end up with something that will keep your own morale up. There is a reason they used to give us chocolate, gum, fudge, etc in our MREs. Have to 'want' to fight to go and fight.
Don't forget about redundancy. Everything you plan for or pack, say to yourself, "what if it fails, or breaks, or battery dies..etc." You can bring a small mat to sleep on if you need to at night, or for the same weight, if you live near any sorts of greens, a small axe and a headlamp, will make you own 'off the cold ground' bed. Two headlamps and/or flashlights take up little room. Two mylar blankets, match kits, or tubes of bacitracin take of little room and weight, but can save your life if the primary is lost or damaged. Dehydrated food is light, and usually tasty, but requires adequate water to re-hydrate properly in your body. Also, some I have found leave a strange film in your mouth, like dehydrated ice creams. not what you want be worrying about while you try to survive. Tasty is a good thing, but try them before you need them.
Redundancy at home is also important. backup your backups. If you have solar, have another panel incase of damage or theft. Or, add wind to supplement the solar. Have two generators. The second doesn't have to be as good as the first if too expensive, but nothing breaks while in storage...just when you need it. If you Faraday cage your electronics, have you thought of your generators? What about your heating furnace boards? Both will need to be protected if a situation that requires a Faraday cage happens.
I hope to die an old silly fool with a bunker full of expiring food and unused generators. But, I will hopefully be ready if not.
