Humalog is actually more stable than Regular.  I leave a vial 
unrefrigerated in my pump kit in my briefcase and haven't had any 
problems with it.  In the summer time if it's going to be outside I 
throw one of those cold-gel packs in the kit to keep it cooler.  As 
long as the insulin doesn't freeze or get over 100 degrees it seems 
to be stable.  Since it's in the resevoir in the pump for up to three 
days it had better be stable or we'll be walking around with cold 
packs strapped to us too!  Why do you think that the life of Humalog 
is less than R?   Check out Lilly's web site for details, but 
according to my pharmacist, CDE and doctor lispro has some buffering 
in it that makes it more stable than the regular humalog or humalin 
insulin.   Unless you expose it to extremes like leaving it in your 
car in the summertime or wintertime, or live in the tropics you 
shouldn't have to worry about it getting too hot.
