Still nowhere near 100%, but feeling much more human today, thank goodness! So it was carry on as normal.
As yet we've failed miserably with our intention to do a little in the living room every evening, so we decided to spend most of this weekend getting on with it. MrM spent the morning in the workshop, and in the afternoon and evening finished putting the tongue and groove cladding on to the ceiling. It's been fraught with difficulty and has taken far longer than anticipated. Eventually it will be my job to paint the ceiling white - not something I'm looking forward to, but there are numerous other jobs to do first...
Among numerous other things, I continued applying knot seal to the wood, and helped MrM when necessary to get the planks up to the ceiling.
