Makes total sense.@Quill thank you for the kind words. I've learnt so much from people like @Inka and @Drummer @Leadinglights and @rebrascora . There is lots of information and experience on this site.
Two other things I learned, many people use their lancets multiple times. I have done this because changing each time seemed wasteful. Obviously you mentioned you had a family member who was diabetic I do not share my machine and if I did the lancet would have to be changed. Ive heard it said the two hour test after a meal is two hours after the start of the meal but you will probably looking at trends.
I may re-use if I’m running low and lacking funds as it will only be myself using it but we shall see going forward 🙂
