Do you still bolus at the time of your protein only meal and check two hours later or do you change the time of the bolus or duration using square bolus (if you pump)?
The reason I ask is I just had primarily protein only meal (5 g carbs for me, which I covered with a unit) and my blood sugar stayed level at my pre-meal reading for two hours and then suddenly just increased by 30. I've checked my basal rate recently so that likely isn't an issue, and wasn't sure what was up (or who to ask!) until I read this.
