Hi, i definitely won't be eating a whole pie. It would be just a slice or twoHey.
I'm about to fall asleep so I'm not gonna search for it myself now, but there is a video by Gary Scheiner explaining pizza and insulin. Just google it. I'll look for it tommorow.
I've tried everything, but pizza is really tricky! Even 50 units of regular insulin aren't enough for a whole pie sometimes (they easily have 200g of carbs or more)
Just keep trying and don't give up!
