Plastic bag, zipties and melatonin/sleeping pills

[Clean]

Hi, this is my first post so im not sure what prefix to assign to it. Does anyone know how well a plastic bag over head, some zipties and sleeping pills would work and how painless it would be?

From another thread,

"SI will definitely kick in. Even if you manage to make yourself pass out, your KO'd body will probably rip it off your face, making the attempt unsuccessful. To do this and succeed you would need to tape it all around your head, and maybe even handcuff yourself. Near impossible for this to work and will be very painful. Sorry. "
