it's dying from side effects like respiratory depression and not dying from a poisonous lethal dose.
no way to make sure it works, i thought about taking 500-1000mg of benzos combined with other breath depressing substances (opiates,barbiturates,alcohol,GHB?) and antiemetics plus other methods to reduce breathing (like a bag) on a place no one will find me for some weeks, but i guess it's still a 70:30 chance to die or something like that. ketamine acts also breath depression supporting and the benzodiazepines should suppress hallucinations and bad feelings from it but thats just theory, a little bit of ketamine won't support and a full K-Hole acts very strong. don't want a trippy death
