Good to know that the BD 4mm needles are still being prescribed. It does seem a case of badgering the surgery if the needles have been changed, but personaly I've given up for the moment and bought some from the Diabetes.co.uk online shop. Just over £50 for three boxes (VAT-free), and these will last for most of a year. I don't mnd the odd £50 now and agan, but I might try again at the surgery when these run out (as I'll be retiring next year and going onto pension!).
Slightly off topic with the insulin pens again - just had a phone call from the surgery confirming that the prescription has gone back to five pens. No explanation of why it was changed, but, as PaulinaB suggests, it might have been that they were thinking of two boxes. The surgery's been pretty amenable so far, so I'd like to think they were trying to be helpful rather than vindictive.
Just to add that my local council deals with sharps bin collections, and they also provide clean bins - one size only (large). I had to register with them, but once I'd done that, it's simply a case of ringing up when I need one changed. I found out by logging onto the council website.
