@Tim – thanks, and thanks for the [insert witty anology] advice 
@Clara – you would of thought the NHS warnings would of led to some sort of recall or led my diabetes doc to warn me, but nope! My diabetes doc still gave me a prescription for it this afternoon.
On the subject of pens of other types, I got told today my Novopen 3 was defunct, should of been moved onto the Novopen 4 by now. I’m starting to think my doc might be a bit behind times …..
I’m going to play both sides I think and get my GP to write me an Autopen up and take it from there. Despite the warnings, I’ve personally not had any problem with the Optipen.
