I can report right here that last night I had the very, very worst night's sleep.
I slept in fits of 20 minutes before waking up with a start, convinced I was late. One one occasion I woke up at 4.20 furious with myself because I only had 10 minutes to get to my job in Newbury. Only when I was sprinting down the stairs did I realise that I only work in Newbury on a Sunday morning and this was, in fact, Tuesday.
Right now, I need to run about and keep busy otherwise I will be asleep within seconds! Ridiculous!
