I missed mine for some reason last year... and when I went into the pharmacy to order more meds, I basically was told to have it right now.
I did protest a little as I was trundling down to Pompey the next day for a round of golf. Then again - I dare say given that my handicap is essentially my bag of clubs, it wouldn't have made much difference!
ETA: Just had an automated text from the surgery and tried to ring them to tell them I already had it. They are furious... automated text has just jammed their switchboard!
I think I have had them since 2017 and missed it in 2019 so since my T2 diagnosis ... and deffo flagged for it since I turned 50...
