I woke up at 11 am on Wednesday and haven't been to sleep yet! This is because I couldn't get to sleep on Wednesday night, had to leave the house at 4.30am on Thursday, Can't Sleep On Planes (TM), and was too tired to remember to put the drugs that actually knock me out in my hand luggage.
I was unconscious very briefly on the plane from London to Chicago until the baby behind me cried and I couldn't get back to sleep again. Nor could I fall asleep at all on the plane from Chicago to Seattle. It is now 4 am on Friday in London. I can't even do the math for how many hours I have been awake!
Going to sleep very soon :)
