Thanks for that! Makes complete sense now. Will get the cheaper ones next time as £20 for 30 Swanson ones is not great. Yes I’ve got a Libre but will find out in December if I qualify for the sensors on prescription, as it’s been a game changer for me. I’m a classic panic eater as a teacher and would love that reassurance that even if I feel hungry in front of a class, it might just be hungry and not hypo!? My husband works nights and I don’t sleep due to nocturnal hypos for 43 years so fingers crossed. Do you have one? How have you found it? X
