And then...

 Oh, the irony! The morning after my first experiment with the health-giving elixir Cynar I woke up with a weird and disorienting visual impairment. Ever alert to the post hoc ergo propter hoc fallacy, I drew no connection between the drink and the symptom, but decided I had better break the habit of a lifetime and see a doctor. I managed to secure that precious thing, an urgent appointment, and this resulted in a session of telephonic triage and a prompt referral to the local eye unit. There my eyes were tested at punishing length and found to be perfectly all right, and the baffled medic referred me elsewhere. I staggered home feeling thoroughly unwell, continued to do so for around 24 hours, then woke this morning in my usual state of butcher's dog-level fitness. Today I have an optician's appointment, which seems more than a little de trop after all that. More investigations will follow, but this is the last I'll say about the matter – I'm sure none of us wants this to turn into that kind of blog...
