My first thought was that Smiley might be a fan of The Comedian.
As someone's who's been planning his own suicide for about 6 months on & off I think for painless suicide, Nembutal as u mentioned fits the bill. You could travel to Mexico, Peru, Thailand I think the full list was & buy it there. You should buy the peaceful pill book first tho, it has regularly updated info about availability. Some ppl imported nembutal powder from China too iirc. There are some alternatives to Nembutal but idk what they're called anymore. & ofc this post is only for educational purpose, etc. http://alt.suicide.methods.narkive.com/jXxgf4kH/pentobarbital-aka-nembutal-in-mexico-available-confirmed

also consider whether you really wanna die in a place like Mexico. If reincarnation is true & one reincarnates close to where one dies, would you really wanna reincarnate in a shithole like Mexico? But smuggling the Nembutal outta there has its risks too so may just wanna travel to some desirable country where you can acquire some guns to blow your brains out or sth.
Post some suicide selfies or something, make me a suicide-fansign. :)
Also as far as pills and liquids, if it kills you to drink it I very much doubt it won't hurt. Pills in general cause discomfort in your body, and OD'ing ALWAYS sucks. Mixing can kill you but it won't sneak up on you. Plus with these things it's possible to survive and live your life from a bed, maybe even as a retard. The suffocation by various gas (like helium) is probably the best since you will be unconscious. A large bag full on your head and tied off on your neck so very little escapes? You can buy a huge balloon from a store and then leave whoever finds you a traumatizing message. Happy birthday! Bleeding out will be somewhat painless but I imagine it would be very cold towards the end.
BTW you're gonna shit yourself.
0_o Plastic bag death. Ew.
Rig up a guillotine. Just make sure the blade is sharp enough and heavy enough to do the trick in one split second motion. Otherwise, the experiment could be messy. Not to mention the pain and the freakshow if you actually live through the failed attempt.
^That's how I would choose to be executed (in the most hypothetical hypothetical ever of course.) It's completely painless bc the spinal cord is severed instantly.
Also, strangulation isn't as horrible as most people think. I used to do it when I was a kid bc I liked the weird tingly feeling before I passed out. Without a rope, your hands just fall and the blood goes right back to your head. With a rope, death would happen within a few minutes. Just make sure you'll have complete privacy for at least 15 minutes. If anybody finds you before the job is done, they'll try to revive you. Brain damage from lack of oxygen is not a pretty sight. I believe brain damage sets in after 5-7 minutes of oxygen deprivation.
Oh, and you shit and piss yourself when you die. Better hope your crush isn't the one to find you ;)
i've heard of something called ligature strangulation, read about it on /suicide/, how it's supposed to work is you compress the carotid and jugular veins with a cord or something, and it cuts off blood to the brain. apparently it's painless and somewhat quick. i say supposed because i've never gotten it to work myself, but i'm probably doing it wrong somehow.

i've tried suffocating myself by putting a plastic bag over my head, it was horrible, after a minute i had the unbearable sensation of air hunger and had to rip the thing off my head. i think you meant to say carbon monoxide, that's a good way to die if you have a car or a grill or something.
