Needed: more sleep!

I feel tired and run down for no real reason. I don't feel sick but just really tired and as if no matter how much sleep I get I am exhausted. I know I can still improve my fruit and vegetable intake even though it is heaps better, so I know I can focus on that, but I had about 7hrs sleep last night and I did my walk this morning and I feel like I could go back to sleep for another 3 or 4 hours. I sure hope I am not fighting off a bug of some kind.

I'm wondering if I need more sleep now that it's the middle of winter? I mean the days are shorter for a reason aren't they? Maybe I need to increase the sleeping hours at this time of year. I'm considering not heading down to the track tonight so I can try to get to bed at about 9pm.

I was feeling so good a few weeks ago, maybe it's hormonal? I dunno, but what I do know is that today is going to be a struggle if I don't start feeling like I have more energy soon.
