Bloody MF melatonin. It’s totally bizarre sitting down at 5 in the afternoon and having your brain go ”right, by my reckoning it’s 1am, way past your bed time young man” and to then want to go to sleep, and then at 4am have the opposite, with your brain going “allrighty, midday, well and truly time to get upâ€.
It will presumably sort itself out (and since the universe loves irony, it will probably happen some time 2 or 3 days before I leave to go back to Australia. I can imagine that the first few days of trainee internship when I get back to Brisbane could be interesting as a result).
