You have to be prepared for the very real danger of ending up in a permanent vegetative state instead. Depending on other factors, 100 units isn't even that much.
It's wreckless to suggest just anyone can pull it off like it's no big deal, and like I said, it's not something I personally care to risk. And that's saying a lot, because I'm feeling very suicidal right now with a ton of insulin at my disposal.
If you do it, good luck.
