i know there are compassionate release programs available to help with supplies of insulin in Canada. Generally they are able to give you 6 months of free supply. I am not sure if that's available in the States or not. Your best bet would be to go to a diabetes clinic and ask them. if it is available, the diabetes educators in the clinic would be able to sign you up for the program. Best of luck!
I'm sorry I don't know the answer to your question, but if you send me a private message I will give you the urls for two websites with many more diabetics and someone will have suggestions for you.
