I am so tired today. It has been creeping up on me gradually for a while. Started with a cold I had a couple of weeks ago that made it difficult to sleep and then I seem to have got out of the habit of sleeping properly.

I have no trouble nodding off quickly at night (by then I'm dark tired and fall asleep as soon as my head touches the pillow) but then I wake up early in the morning, not fully rested but unable to get back to sleep.

One night is fine but this has been going on too long - I am looking so tired and every year of my age.

No good eating well and exercising if you still look like the living dead.

Not sure what to do about this. Any ideas?
