I don't know if is hard or easy die from chloroform overdose. Sure can kill you, but I have no idea about the dosage. But try partial hanging huffing chloroform to help u calm down and keep in your position. Particularly I've tried partial hanging very drunk and huffing my favourite inhalant (paint thinner with diethyl ether) but I still a coward, even hardly intoxicated. I hope u catch death.
