I've just realised this, took me a while. For the last five years or so I've been getting up at stupid o'clock (read 5:30am) so that I can get to work in time. Every time someone at work hears that they say "I don't know how you do it." My reply is always, "You get used to it."

No you don't. You don't get used to getting up at the same time you used to get home from a night out, you definitely don't get used to barely seeing your house in daylight even at the height of summer. You don't get used to it.

Can you tell I'm tired?

I left work before I had the chance to say this last night - good luck engelsteorra! You'll get it I'm sure!
