Hi! I had a weird scenario yesterday…I had my site in for a day already and it was totally fine but then out of the blue I woke up at 210 and COULD NOT get down for the life of me. After 4 hours of over 10 units of insulin, I was still at 300. I did a new site and everything was fine after that! I just found it super weird that the site wasn’t bad from the beginning, rather it took 36 hours to stop working. Does anyone have any explanations/experienced this before?
