We are are 3 whole days in and still alive. I might be crankier than usual but that could also be because I have a cold. I don't think the getting a cold came from a lack of coffee, but one can never be sure!
Perhaps it wasn't the best of timing, since we are both participating in the Bluenose run this weekend. But mornings seem to be treating us okay and afternoons are the toughest.
Because we are not complete masochists, we have replaced coffee with tea. It's not quite the same but drinking warm liquid that has a smidge of caffeine helps a bit!
