Method What should I do?

[SamuelClemens400]

I'm broke again, so I guess I'm not gonna catch the bus very soon. I was planning on using CO poisoning, with the charcoal method but no money no charcoal. I'm not sure I really want to do it that way anymore anyway. I am afraid that lighting the charcoal will cause too much smoke and draw attention :/. So now I think I will be trying SN even though I can't really get an anti-emetic. I'm not super worried about throwing up. Ill fast 'n stuff before I take it and I have a pretty strong stomach. I just need to know one thing. What are the odds that I will convulse when I'm unconscious? Id like to die in my bed but if I will convulse I have to take measure to prevent discovery since I don't live alone. I am also an epileptic if that matters. I know when I got choked out by a rope I started either convulsing or having a seizure which drew attention to my roommate.
EDIT might just have to go with CO poisoning because I have 0 idea how to get SN in the US and I know I can buy some charcoal
