To be honest, if you prefer the orange luco, you'll still be able to use the new stuff, only you'll have to drink a bit more than the old stuff to get the same amount of carbs. It's still got plenty of sugar in it. I've always tended to use the pink lemonade version, works fine, and it's always been about the same as the new orange version.
Saw some of the new orange stuff in Tesco today, 8.9 g per 100ml, so about 110 ml for 10g, which'll do fine for most mild hypos. Sure, that's about twice the old money, but 110 ml is still only about 2/3 of a water cooler cup, so we're not talking huge amounts.
Ain't much difference between scoofing a third of a cup and two thirds of a cup that size!
