The second time, now the delivery has arrived, I have laid in bed for an hour and my brain would not SHUT UP with things that need doing. I was composing LJ posts and emails in my head and then having to make a note of them (or the subjects, at least) so that I did not forget them whilst asleep. Not that I got to sleep. I have sent the most important email now that I have given up trying to sleep to write things down.
I do seem to have a nasty headache now, probably due to tiredness and stress. I will take $painkillers and try again to sleep.
