I'm not sure what inspired me to make a pair of complementary diabetic characters, but there you go. Unfortunately, (or fortunately, as the case may be,) I'm not diabetic, and the people I know who are I'm currently out of contact with. My Google-fu skillz, and my talent for checking bottles, gave me the basic lowdown on the expiry times of bottled insulin; however, for the most part they only relate to the stuff that is kept in a refrigerator and treated very carefully.
Diabetic Character Number One is always obsessively careful with his insulin, but he has the bad luck to be dragged into another world where such things don't exist; he has the good luck, though, to be carrying his insulin with him at the time. The climate here is fairly cool - I can't make the conversion from Celsius to Fahrenheit, but the average daily temperature would be about sixteen degrees Celsius and the average nightly temperature about three. He has a backpack, and material to wrap the bottles in so that they won't be broken.
Anyway, my question is - how long would insulin (he has the fast-acting stuff and the slow-acting stuff, if it helps) last under these conditions - unrefrigerated in a coolish climate and being shaken about a bit? If it wouldn't last at all, I'll have to think of an alternative; if it would last a little while at least, how much would he need to last him about four days, give or take a few hours?
If this shows insufficient utilisation of appropriate searching facilities, please feel free to bring the virtual smack down upon me. (You can't bring the virtual smack down on me for not knowing anything, though - I know that I know nothing and therefore a great deal less than the average member of this community. XD Please be kind to me, I just couldn't find the information.)
ET: Love you guys. You told me everything I needed to know, and more that will also come in handy down the track. Thanks again!
