well after a very good yesterday and alcohol late last night , my libre says overnight average 4.1 with low of about 2.2 - having said that its the first night of my libre and it seems to suggest I have lows precisely every two weeks on a new monitor - so I am quite happy to ignore that !
4.4 this morning after a 12.2 last night due either to a cannula failure or bad insulin, that a problem with the pump, as you have no background insulin when something goes wrong the blood glucose rise is fast.
