Far more since my hip replacement as I’m no longer woken by pain at regular intervals. I’m rarely asleep before midnight, generally wake for between one and three hours about 3am, and then back to sleep for another three to five hours. So somewhere between 6 and 9 hours, I guess, but it’s not the same amount every night. I am very rarely tired during the day, so assume it’s enough.
HMRC slightly angry is an understatement
