Is this based on a true story?   My experience of people with diabetes
(certainly type 1) is that insulin dependence is not an optional, they'd
simply feel better type of situation. life of death from my experience, and
if the patient becomes insulin dependent in type 2 - i'd imagine it's very
much the same...
