I'm type 1 and eat rice and pasta, brown rice and wholemeal pasta at that without massive sugar spikes but I'd inject a second time around 90 mins after food, I also wash the rice/pasta in cold water when cooked and reheat it to serve as it seems to lessen spikes, I eat wholemeal bread too and my last hba1c was around 42 or 6%
I'm unsure of the rules but a cgm during for/pregnancy was being talked about pre coronavirus
