Sleeping Patterns.

Got up at 7am this morning, better than the 6am of late. My sleeping patterns are all over the place at the moment. Some nights I don't sleep at all. Hmmm it's doing my head in. It wouldnt be so bad if I was getting 8 hours sleep but it's around 5 to 6 hours. I do need 8 hours to feel refreshed. Sometimnes it's only been 3 to 4 hours sleep. Maybe it's an age thing lol.
