No idea why, just that I know he didn't self ban because you can't self ban in a matter of minutes or hours.
He said he vomited for four hours. He must have meant he was dry heaving for four hours. I have dry heaved for five or ten minutes to the point of exhaustion. Dry heaving for four hours? Hard to imagine and again hard for me to believe.
I can't find him ever claiming that he vomited or dry heaved for four hours straight, just that he thought he had vomited all of the SN up, as nothing more came up. If you have a link to him claiming he vomited for four hours, I would like to see it but I could not find it.
Then he said he was in a coma for 20 hours. So some SN MUST have been absorbed.
SN was absorbed, yes. The doctor informed him of that. It is likely he would be dead now had he never called an ambulance
he went into a coma in the hospital?
Yes. Altered consciousness, coma and death are all effects of SN ingestion.
And why would he be transferred to another hospital if he was in a coma?
He was transferred to a psych ward after being stabilised, likely in an ICU or other "regular" hospital ward. He was conscious at the time of transfer. This is normal procedure for suicide attempts.
Here are the things he claimed happened to him:
1. he was vomiting for four hours
He didn't claim this.
2. he was given the antidote - as much as they had
Yes, methylene blue is the standard emergency treatment for SN poisoning to reverse methemoglobinemia.
3. he was in a coma for twenty hours
Yes.
4. he was transferred to another hospital to have his stomach cleaned out with charcoal
I don't know what they cleaned his stomach out with, but being transferred to another hospital or ward within the same hospital after stabilisation from a suicide attempt is standard. Psych wards aren't usually equipped to handle patients who are in medical emergency.
Was he vomiting for 4 hours before the coma or after or during it?
Don't know, but you can vomit while you are passed out. This is how some people who overdose on drugs die, they choke on their own vomit while passed out.
But was posting the next morning? After all that?
Hospitals usually keep a person's personal items by their bed, so once he woke he would have had access to his phone. They have no reason to take it. He was clearly still in distress, but said himself he wanted to update the people worried about him.
But he couldn't keep enough down to ctb. Sensitive stomach and all that.
He likely did keep down enough to CTB, but he called an ambulance as he had decided for himself that if he vomited all three glasses, he would call for help. I still do not know why you doubt his sensitive stomach story, he has been saying for a long time that is how he has access to metoclapramide.
And the hospital is across the street and they have keys to his apartment.
It is not uncommon for a landlord or body corporate of an apartment complex to have a master key. In the event of an emergency, obviously this key would be given over to the emergency services. They may even have a master key for local apartment complexes in the hospital.
