Spoke too soon. Just tested and it’s up at 24.7. With 0.9 ketones. Ouch. I’d changed my set after breakfast, so the breakfast dose had gone in OK. The new set, however, was as bent as a very bendy thing, and then some. So I hadn’t had any more insulin going in since about 9am. Manual injection by pen, same amount bolused through a disconnected tube, new set plumbed in (don’t forget to take off the covering from the sticky plaster – I did and just punched a large bloody hole in my side). Mopped up the results, got yet another fresh set and this one is now attached. Fingers crossed this one’s gone in OK.
