ODing with ketamine primarily (+benzos, opioids)

[Lifeaffirmingchoice]

I don't know if @Proper Overdoser still responds to inquiries, but anyway, what combo of ketamine lozenges, benzos (valium and xanax), and, if needed/advised, hydromorphone and/or hydrocodone would be a successful ctb? I have read the opioids thread but i'm not looking to use opioids primarily as the agent that induces death. Rather, it would be ketamine. Any guides or info out there as to how much to take, and what to possibly add? I also have available: unlimited alcohol, unlimited rx and otc antihistamines, rx anti-emetic (ondanestron and I could probably easily get any others)
