The two threads mentioned will be a good start.

One thing to always keep in mind in planning for any survival scenario is to ask "what can kill me the fastest?" Then plan to avoid that (whatever it is) as the first priority.

Thus, in a desert, survival is first dependent of water, as you are likely to die of thirst before starving to death. In the arctic, warmth is number one, because you will freeze to death before you die of thirst. And so on. Doing something really, really, stupid will always kill you faster than anything else.

Think about meds the same way. A diabetic needs insulin to live, and must have a supply. OTOH, if your taking a "statin" because your Cholestrol is 250 without it, doing without it for a week or two or a month, probably will not kill you, even if it is not "good for you." So, I would not worry about taking a 2 month supply of lipitor with me at the cost of some spare insulin pens. . . Decide what meds you need to keep functioning, and which are only "good" for you, and prioritize.

as always, YMMV
