Morning everybody. Over the last few weeks, I'm not only waking constantly through the night, I'm also waking up at 4.00 am and finding it impossible to go back to sleep, so end up getting up. I'm exhausted, but I just can't sleep. I'm sure I'm not the only one who does this. What do you do with the time if you too are up this early? Do you use the time to do something constructive, or just sit around feeling fed up?
