If I've got a Libre sensor on, and can see I'm heading towards hypoland, a banana or dates will do it quickly enough for me, but if I'm suddenly really low, it needs to be jelly babies or fruit pastilles, for the instant glucose hit. Problem is, brain fog descends when seriously hypo, and I have been known to stand dithering in front of the cupboard with a vacant 'what shall I treat it with?' expression on my face, so having a regular, known 'go-to' is probably the best idea, I can normally give myself a kick and tell myself just to get on with the JBs or FPs.
