i used to fully load my pump w/ insulin so that i didn’t have to change it for almost a week at a time. ended up w/ high BG(bad absorption after the 3rd day) and lots of scar tissue. i also had the bumps on my tummy. but what i was doing was finding a “good” more comfortable spot to insert my introducer needle; i ended up favoring certain areas. then it just went on and on like this for years. now, since i’ve been on the dexcom cgm, i was able to see the trends in my BG. now i fill my reservoir for 2-3 days and rotate, rotate, rotate. still, my favorite sites are my lower abdomen. also, now i am on the sensor and i need to rotate that as well. its like being on a roller coaster sometimes.
