Method Is Inhaling Helium or any other inert gas a safe and peaceful way to CTB?

[bigmanharsh]

I am a very cowardly individual who while seeks the pleasures from the release of life by death, is terrified of the process at the same time. I really wish to have a painless and peaceful death in my solitude. I live in a third world country with not many ways to CTB around here. I am a smaller individual at only 5'5, so i reckon i don't need much in terms of quantity but i fear for the purity of commerically available stuff. if you have any insights i would appreciate some help :)
