The idea behind CO is that you DON'T want any smoke. You need to light the charcoals in a different area from where you plan to CTB and WAIT until they stop smoking and they start to burn intensely red/white hot. CO is a
colorless and
odorless gas, hence NO SMOKE. Smoke from the charcoals are impurities that will only make your death uncomfortable and harder.
How many charcoals do you plan on using? A bathroom, even a small one, isn't that small of a room. There is bound to be leakage you need to take into account. If you don't do things right, CO can really mess you up if you don't happen to die. Like mess you up so bad that you can end up a vegetable, drooling on yourself and having your ass wiped by some uncaring nurses aide in a convalescent home. You can actually be in worse shape that you are now, as hard as that can be to imagine. If you screw it up you may be in such bad shape that you will never be able to remove yourself from this new horror you find yourself. I'm not trying to scare you, just telling you how it is. Whatever your plan is, you need to make sure that you get the CO level high enough to cause death, not merely harm.
Have you read this Megathread? I suggest you do. I also suggest you get your post count up so that the "Search Function" on this website will reveal itself to you so that you might investigate this method better and learn more about it. The more knowledge you gain, the more likely you will have success with it if you should try it.
CO Megathread
I thought about that:
1. I'll use melatolin or something that makes me black out in the bathroom (Something that doesn't go so fast, I want my final moments to be good)
2. I'll light a barbecue inside the small bathroom, waiting for the smoke to build up.
3. After the smoke grows in large amounts, I will go into the bathroom (trying to handle the temperature that will be in the bathroom, but this is easy to solve.)
4. I'll try to stay unconscious.
I will probably die of suffocation. But since I'm kind of crazy, I'm too scared to do that. Can anyone tell me if this plan is any good. And also, if I need a different coal to be able to commit suicide.
Anyway, just tell me if I'm being silly or everything is okay and this idea might work.
