Has anybody here survived carbon monoxide poisoning?

[failure383]

Until recently, I had no doubts that CO poisoning if done correctly is a peaceful, painless method with high chance of success, however I found some resources, which make me question it. In particular this website seems to provide information on that issue:

To quote

After observing several dozen CMA victims in autopsy, I can tell you that the body left behind is useless for organ donation, discolored to the point where extreme make-up is required to prepare it for any burial viewing, and is treated as a toxic waste product by professionals. None of the CMA bodies I saw had that "classic" peaceful facial appearance, similar to being asleep. Rather, some had their eyes open wide, while others had a horrific grimace, swollen tongues protruding out from stretched lips and most had suffered some degree of nasal haemorrhaging. All but a few had vomitus spray on their clothing and most had experienced trauma related bowel release syndrome, (T.B.R.S. also called 'timber syndrome' by industry professionals).

All the survivors expressed pain and sickness during their CMA suicide attempts. The statistics are exactly even regarding mental and emotional pain, but 100% described the experience as worse than being slowly killed. The majority described the events as being similar to being tortured to death, but the CMA symptoms hampered their ability to stop the events once they found themselves in the agony state of CM poisoning.

A full 25% stated that they had decided to abort the attempt when the physical anguish became unbearable, but had lost the mental capacity or resolve to abort. Of all the survivors interviewed, 82% stated loss of bladder control and 34% of those expressed intense shame at having wet themselves while still mentally able to realize the situation was going to be agonizing and now messy.

I'm very aware, that this is just some random blog from 2009 mirrored on the Internet Archive, quoting some nameless, supposed specialist, but since I want to be really sure, I want to know if the experiences of the people here, who survived CO poisoning were anything like this.

Other resources like the PPH by Nietschke (who the above article is a critique of) say it's peaceful.

If the inhaled concentration of CO in the inhaled air is high enough, a rapid peaceful death will result.

The ASH Wiki is rather nuanced (which I don't know if it's a good or bad thing) and claim it's neither peaceful nor absolute agony and states the potential discomfort, one might experience.

Carbon monoxide (CO) enters the bloodstream through the lungs and attaches to hemoglobin (Hb), the body's oxygen carrier, forming carboxyhemoglobin (COHb) and thereby reducing oxygen (O2) delivery to the body's organs and tissues. High COHb concentrations are poisonous. Central nervous system (CNS) effects in individuals suffering acute CO poisoning cover a wide range, depending on severity of exposure: headache, dizziness, weakness, nausea, vomiting, disorientation, confusion, collapse, coma and death.

As you see, I'm really not sure who to trust on this issue and I would really like to have answers on this subjects, since it still is my method of choice.

If you use the search you can find threads from people who survived their attempts.

Of course there are some "reported" failures. I put reported in quotation marks because like everything else you read, everything is anecdotal.
