I am well controlled having 8 units a day of Novorapid and 22 units of Glargine a day. I have a Libre 2 which I find exceptionally useful. Since the start of the current very hot weather I am daily having lows of a range from 3.4 - 4.2 which is not normal. What should I do to keep my blood sugars up as I already take a break around 11.00am of 3 biscuits and a tin of ginger beer. It does not stop my sugars dropping like a stone.
