If I don't wake up at that time, or if I do wake up and manage to get back to sleep for a while, then that is an exceptionally good night and I feel great all day. Full of good cheer (well, mostly) and reasonably energetic.
But 80%+ of the time I only get 5 hours sleep. I feel and look like hell!
What can I do? Its too late in the morning to take sleeping tablets (I have to be up at 7am). I can't understand why my body keeps waking me up when I am SO fucking tired.
