I brought back a cold with more from the UK, and frustratingly I can't seem to shake a cough. The combination of cold and jet lag is really doing a number on me. It always takes me a while to readjust after a trip back to the UK, but it will probably take me even longer this time. I'm not sleeping well and I'm nowhere near returning to sensible patterns of waking up, eating, working and exercising. I should not have returned to work immediately after my trip, but since I took so long off I didn't have a choice. And I certainly don't have the patience to deal with any Halloween nonsense tomorrow - I'm not expecting any trick or treaters, but who knows who might show up.
