I wished I'd never done it. After reading a few threads saying how humane it was and that they wouldn't suffer I decided to use this method on my adult EE. She needed to be put down because she had been unable to move her legs for about six months, had stopped eating and was losing weigh. So I wanted to end her suffering and could not afford a vet. Well don't believe them when they say that they just fall asleep. They don't. They suffocate to death and it is horrible. I cried my eyes out for what I did to her. I had to listen to her pecking at the lid to get out. I'm just plain sick over it. I agree that breaking the neck or cutting it off would be the best and fastest way to end it. Don't do what I did. It's to cruel.
