I mainly use Jelly Babies; I find Dextrose tablets a bit unpleasant. There was a brief period in 2021 when JBs were in short supply from our home delivery supermarket, so I looked at options. Fruit pastilles work well, not much difference in price or carb content to JBs.
Then my 8yr old grandson introduced me to Haribo sweets; proved to be really good. As well as buying bulk packs they come in small pocket sized bags of about 9 sweets and providing 20-25 gm CHO (there are different types of Haribo and it depends on what's in any one bag). Just before Halloween, Haribos were on sale everywhere, in bulk quantities of the small packs for "trick or treat". Amazing value, worked out at under 20 pence per 100 gms, or about 5 pence per bag. They also provide a change from JBs, which can be boring when hypo strikes are too frequent!
