Since getting a prescription in Portugal, I had become complacent about my HRT stock. Previously, I maintained a stockpile of between 6 and 12 months' worth.
I figured this was no longer necessary, as Portugal isn't being so comprehensively weird about trans people as the UK, and also they don't officially know I'm trans.

I was shocked out of complacency last month due to a supplier shortage. The pharmacies ran out.

@Zoë O'Connell and I got within 10 days of going cold turkey.

Lesson learned. As of today, and thanks to the grey market, I have 5 months' worth, and that will soon be getting upped to 7.
