Hi aitch
Fergus is right - rice will be the culprit. Even though basmati is low GI it will still raise BG by same amount, might just take a bit longer to get there,
Novomix has some benefits, but not being able to correct or shoot enough to cover a planned meal is the major failure.
I was happy to wait until honeymoon period over but after a couple of days of unexplained higher than norm bg(maybe honeymooon is over?) I cant wait to change regimes.
I find my short acting bit of premix is not good at covering meals and any deviation from portion-type or size, will see you go higher. Intermediate acting bit is a bit better but still not great,
Keep at it, you will see a difference
