I'm going to bed in an hours time so that I can get up for 5.  Jo and Ellie are away for the week so I should be able to get a lot more done around the house and my fasting will be much easier.  Still not suffering with hunger or tiredness.  Weight-loss has been steady so far and my sleep pattern appears fine at the moment.  Will see how the early mornings of a set of early shifts affects me.
