So no more leaks from the toilet cistern since I tightened up the compression seal, which is a relief.
And it increasingly looks like I did pull off the wrong Butec patch last Friday, leaving myself wearing one four days expired. I put on a new one last night and feel much better today. Not totally pain free, I think a few muscles are still knotted up, but much closer to my normal. Though it occurred to me yesterday that needing to spend days lying flat in bed in significant discomfort used to be a regular thing pre-Butec, maybe as often as once a month. Regular exposure to that level of pain is why I completely didn't notice when I came down with Acute Pancreatitis, despite its reputation as one of the most painful conditions known. Ironically yesterday must be just about the anniversary of me realising I was in trouble from that and having to dial 999. (It's definitely not a recurrrence, my gall bladder having been terminated with extreme prejudice).
Like my tag says, better living through opiates (I know it technically should be opiods, but close enough)
Fortunately familiarity does mean I know how to deal with days like that, so I curled up with a good book or two (Cherryh's Precursor and Bujold's Cetaganda), though unfortunately I was lacking a decent bottle of wine to go with them. I should have made up a batch of cocktails of some description now I think of it, though I'm short of mixers given the recent UK-wide shortage of CO2 for tonic water (seriously, this is an actual thing that hasn't fully sorted itself out yet, at least at the non-Fever Tree end of the tonic water market)
And hopefully I finally get my Covid booster this evening.
