I'm sure my readings fluctuate during the day, but I'm only reading 2 hours after my evening meal. I'll keep an eye open though.
I'm quite pleased with how easy it was to drop out of the zone around 10. If I think about it I've just cut out the sugary squash, white bread, white pasta, cakes, chocolate, doughnuts, pasties...and most of all big portions and second helpings. I seem to have developed an obsession with food labelling...Aaargh...I'm a food anorak!
Takes a lot of willpower but I'm getting used to it!
