My mother was losing her eyesight, had vascular dementia, and neuropathy that hindered her ability to walk, and was double incontinent.
I then developed non-diabetic peripheral neuropathy a few years before my diabetes diagnosis, the cause of which wasn't discovered in time to prevent permanent damage, so any addition damage could stop me from walking - although I am more scared about losing my eyesight as I'd have to give up my freedom without my mobility scooter.
Sometimes I am tempted to give up a strict low carb diet, and I've had a few 1 or 2 day wobbles, but having seen the consequences first hand I know how serious this can be.
