Having just finished reading One Second After, I'm wondering are there any viable natural alternatives for insulin. Potentially will have a Type 1 family member in our group and would like to have viable back-up Meds available if possible. We are currently looking at a 6 month supply that will be rotated but hope to build supply up to at least 1 year if possible. Shelf life seems to be an issue. We have a secure, safe, sustainable, and constant 55F storage area for the insulin. One other issue is getting a large quantity 'scrip to start with. Not to mention buying the extra supply at full cost since the insurance won't help with a "stockpile." Doctors and Insurance companies are both royal PITA.
