For some years I have taken medication to control mild blood pressure problems - and believe me, if you lead my sort of life, you would not find this remarkable.
The tablets, sealed in silver foil, are imprinted with the days of the week, so the doddery among us can clearly recall whether we have swallowed our daily dose.
It has all worked well, until recently, when I renewed my prescription.
Suddenly, the silver foil packets are no longer available, as Pharmac has decided there is a cheaper substitute available to fill the prescription.
Now I'm given a box full of microscopic tablets, probably produced in some dubious part of the world, providing a low-cost copy of my well-proven drug. One could argue there's a legal argument here, about restricting consumer choice, but as usual there are more important matters to get on with, like writing this column.
