Not so much ill as just not 100%. For some reason I did not sleep well last night - getting to sleep late and waking up early - which is unusual for me. I shall probably feel better once I've had a meal and a decent night's sleep tonight. I wasn't worrying about anything it was just my brain would not switch off. I think I'd better go back to reading fiction - the lighter the better - late at night otherwise my brain is just too active for sleep I think.
Maybe a longer - and more interesting - post tomorrow.
