Can you die from a toxic and terminal sugar overdose?
Answer:
For a healthy body near a healthy pancreas, you would probably not die. You might gain sick and start vomiting, however.
If you eat sugar and sugar exclusively, you'll be dead--but it will rob some time. If you don't permit yourself hose down or other liquids, you'll be unconscious in a few days, possibly a week at most. A diet of only sugar near water will give somebody a lift a bit longer, but the variables make an accurate prediction alll but impossible. If you gorged on sugar, you might live a week or two. If you restricted your intake, perhaps you might live as long as three weeks to a month. Whether you'd die of some dreadful pancreatic and other organ shutdown or starvation from absence of nutrients (mostly salt) would be a toss up. But one thing's for certain...it wouldn't be "sweet".
You would puke and become nauseated first, so unless you have an IV drip running dextrose (which would make you nauseated, still), I can't see how you could seize the sugar in anyway.
I believe that's what "lethal" and "deadly" mode...
