I was in hospital a couple of years ago (pre-pump). I flatly refused to let the nurse give me the insulin injection, because, frankly, I didnt trust her (or rather what she’d been told) to give/be the right dose. We compromised – she drew up the dose, I checked it and gave it myself while she watched. But I do dread having to go in and deal with all that on a daily basis, particularly if unwell.
