Late in reading this, but great post, Nicky. The sensory overload sensations you describe occur with my lows, sometimes (usually when at home, with lots of competing voices, music playing, etc). It’s taken me some years to realize this…or maybe it is a change in low symptoms over time.
I too, have had the visual disturbances with certain lows. Not very much fun, especially since they remind me of migraines with aura, which I’ve also experienced (thankfully less frequently in recent years).
@Bill brought up low symptoms changing over time…I’ve definitely noticed this. I posted most of my typical low symptoms in another thread, many of which weren’t exactly textbook low BG symptoms.
Maybe we ought to have a sticky with low symptoms as reported by members? Or maybe this already exists?
