Sounds like classic reactive hypoglycemia. T2D livers run unregulated, pumping glucose nonstop, bouncing you from high readings to even higher ones. Mounjaro clears liver fat, making the body more insulin sensitive. Eat fast carbs, pancreas dumps insulin, sensitive body pulls that sugar out fast. Systems like glucagon, cortisol, adrenaline normally kick glucose back up, and GLP-1 dampens glucagon some but still functions when you go low. Went through this adjusting myself. Exercise complicates it further. Had to cut carbs to stop it, so try lower carb and skip fast carbs a while, body should adapt. The crash can make you crave an entire dessert, so I kept glucose chews in my gym bag since it only hit after carbs plus training. Four grams, a single tablet, usually settled things again.
