I am a 72-year-old type 2 diabetic with a lousy memory. I can never remember if I have taken my last insulin shot at the correct time. I've tried keeping a diary but forget to fill in the date and time. I am using Novorapid in a NovoNordisk 3 pen. I have heard there are pens that record how much and how long ago the last shot was but can't find one that is available in the UK. Does anybody know of a suitable pen? Thanks
