Tiredness

I did think last night that I would probably be awake at school time this morning - for the last 2 days I have woken up before my alarm and so suspected I was at one of those points where I am getting the right amount of sleep (they normally last for about a week before I return to the impossible-to-get-out-of-bed stage). I even went to bed at a reasonable hour last night for a Friday - I was away by 11 and slept without waking (apart from to turn the heating off at 1 in the morning because it had been put on boost and the radiators were beginning to moan). I woke up this morning at 11. 12 whole hours of uninterrupted sleep. I must have needed that! Still shattered though... school is exhausting, honestly!
