I use pens and have a Dexcom G6. Yesterday I received the 2nd Shingles shot and the High potent flu shot. I didn’t sleep well, feeling hot but no fever. My normal night time BG of around 85 to 95 mg/dl running as high as 145.
I increased my basal about 20% and bolus about 40%, but BG is not responding properly. A similar thing happened after the 2nd Moderna vaccination. I had increased insulin resistance for about 5 days, before things settled down.
