Hey Blondie, Take a paracetamol if it gets bad and drink lots of water. *and think to yourself, it's working!* I think it Carbohydrate Withdrawal!! I had a headache in Day 1 & 2 but yesterday and today have been great. Not hunger, except in the evenings so I keep busy. In the process of an early 'spring' clean, taking it a room an evening - also keeps me away from the kitchen.
Well done for sticking with it.
