I caught this curse seven years ago (dad was, my aunt was) and have found the number one benefit is exercise. A swim of a half hour walk can improve control dramatically.
Every morning I take my dogs for a two- to three-mile walk/run in a nearby nature preserve. After work I hike out half a mile to catch my horse, hike half a mile back in, ride for an hour (which is both aerobic and strength-building), then walk her around to cool her out. Late at night I take the dogs for another walk of roughly two miles. (They’re thin, too.) I also do weight training, do major home-improvement projects, cut the grass, and garden. Tell me when or how I should get more exercise or lose more weight.
My son’s a highly active diabetic. Activity can actually screw up control for anyone using insulin and cause them to go low at night until they figure out how to manage the metabolic boost.
