can you explain me? how much should i drink,, how does it kill, is it medication that not supposed to be drinking ?
N is the commercial brand of a barbiturate called Pentobarbital. It's a depressant that can serve other purposes such as a pre-anesthetic/sedative. It was even used to treat insomnia at some point. But obviously, we only take an interest in its use for euthanasia, both veterinary and human (in countries where it's legalized). It is also used for the execution of death row criminals in some places.
It causes death by respiratory depression and muscular paralysis, leading to cardiac arrest. Basically, your body slowly ceases its vital functions. It's previously been described as "like going to sleep".
It's considered a painless peaceful death by multiple sources, especially in places that offer assisted suicide like the famous Dignitas in Switzerland. They strive to make the process as humane as possible. I'd recommend doing some research on this if you want to understand how people die after taking N. There are reports here on the forum as well.
I believe meto should be good enough, yes.
