To Sleep Perchance to Dream

I'm off work all this week on holiday and have spent much of today in bed asleep. Now I don't know if that's because I need the rest, or because I'm just very lazy. I think it's the former because I'm still tired. Now the problem as I see it is that I could utterly reverse my body clock carrying on like this.

So, do I go to bed early? Do I balls.
