It's always best to wait out the detox symtpoms mnelsonnh. It's called a fasting crisis and the body usually tries to continue it after you break the fast. It can't do it in the same way so the risk is that you will end up with a full blown flu on your hands rather than just a few symptoms of the flu. Though there's no real telling how your body will cope that's one thing that could happen. So I'd stick it out another day and see how you go.
