Be sure not to freeze your insulin.
How long do you expect the power to be out? A fridge will stay cold for a day or two so long as the door is not left open. Even better if you make sure it (and the freezer) is filled with water bottles, plus pots and pans full of fresh water (another good idea anyway).
As above, even opened insulin is good at room temperature for around 30 days (maybe even longer).
Good luck. Here's (selfishly) hoping Irene stays well to the West of us when she comes through here on Sunday night.
