You will want to stock up on anything you may need as far as pain and fever relievers, any prescription medicines, bandages, anti-bacterial ointments, tooth paste, mouth wash, just anything you can think of. Does your medication need to be refrigerated? Consider car charger refrigerators/coolers. Some are designed specifically for Diabetics.
With electronic transfers down, credit card processing will not be available. Have cash stashed away!
Consider what you have and consider the fact that whatever it is, it may be used to barter later on.
