Hi Kez. I'm also fairly new to diabetes and insulin. Hypos were a real fear. I have had one night time hypo but only knew this as I use the Abbott freestyle libre monitor (expensive but useful to get an understanding of how your levels vary). My diabetic nurse informed me that in the case of a night time hypo you will either wake up with symptoms or your liver will come to the rescue and release glucose into your system. I keep lucozade next to the bed just in case. If you have not come across it on the forum I highly recommend reading Think like a pancreas by Gary Scheiner. Really has helped my understanding of diabetes and using insulin. As your diabetic team about the libretto monitor. I got a free trial pack. But after this you have to buy the sensors yourself. Sorry will not try to help with the first query as not genetically qualified (but was covered in think like a pancreas). Best of luck.
