@furrypaul – a forum thread going off-topic? Who’d thought it? At least we’re not getting into a pedantic argument about the correct use of the restrictive relative pronoun
Anyway, I think as with anything diabetes you’ve just got to experiment. I usually go for thin-crust pizzas as I prefer them, so carbs aren’t too much of a problem. But with my nemesis – fish and chips – I’ll do a dual-wave with 75% in immediately and 25% over the next two hours. I seem to digest quickly, so that seems to work for me. But I know other people with stretch out their dual waves over hours and hours.
