I think we’re definitely on the same page, after your clarification. This is why I say exercise is one of the most important tools a diabetic has at their disposal. It is definitively not a cure-all, especially for Type 1 diabetics. It might, actually, be very effective for some early-stage Type 2s, but that is for another conversation. Regardless, a Type 1 has to deal with the lack of insulin in some way. Exogenous insulin is usually necessary (I’m the weird Type 1 that isn’t yet on insulin, although that’s going to change next month); changes in diet can help enormously (although many people don’t change their diets at all); and exercise can also help enormously. I’m a big fan of using all the tools available.
Incidentally, since you exercise frequently, you might actually be benefiting and not realize it! Many people find that an extended period of enforced inactivity (due to injury, illness, etc.) makes managing their BG a 1,000 times more difficult. However, you might consider adding weightlifting (or serious bodyweight strength building) to your routines! Muscle is far, far more efficient at processing glucose than other body tissues (due to the way glucose is stored as glycogen and used for energy), and can provide a real sink for blood glucose of almost any type (Dawn Phenomenon liver dumps; postprandial spikes; stress-related liver dumps). Glycogen-depleting exercise (sprinting, intense swimming, olympic weight lifting, HIIT or Crossfit, etc.) is remarkably efficient at dealing with free BG (by sucking it up to store as glycogen for the next workout) once your body gets used to it.
And the stress-related BG spikes you have from courtroom activity are real (and related to exercise highs). Stress hormones (even from “positive stress” or excitement) causes the liver to convert glycogen and dump glucose into the blood (and also increase your bladder load). The hormones are trying to make sure you have enough free energy to do what needs to be done… for me, the culprits are: sexual activity; intense exercise; giving lectures related to work; traveling for work; and any kind of interpersonal conflict). Predictable liver dumps can be, for me, prevented or mitigated with resistant starch intake (I use 30g before exercise or giving a presentation, for example).
