I’ve used jelly babies (as suggested by a nice nurse), but find I can’t stop eating them! You’re only meant to have 3 for the requisite 15g carbs and that just doesn’t feel like enough. I tried fruit pastilles too since @tim advocates their use- but I only like the green and yellow ones (and sometimes when I’m hypo I get distracted by stuff- friends have had to make me stop choosing colours and just eat the damn things!), and they take ages to work for me. My favourite cure is still a 150ml can of sugary coke. Liquids, especially fizzy ones seem to work the fastest for me.
