Yeah, I like CO better, as well. Ideally, I would have preferred to combine tricyclics and CO - I think it would guarantee almost a 100% lethality with little risk of pain. But, unfortunately, I don't have a place for a CO method.
And N is a total pipe dream for me, so I don't even take it into consideration.
Waking up in he middle of the process is a big source of concern for me, too. I have about 500 mg of various benzos (plus the sedative effect of amitriptyline itself) and, hopefully, it would be enough.
I tried doing "dry runs" with a bag - putting it on and just getting a feel for it. The first time it felt claustrophobic and I completely panicked. However, after having tried it a few times it doesn't feel that bad anymore. Even sort of cozy. The worst thing is a very strong smell of plastic. I'm using the thickest type of trash bag I could find and it absolutely reeks.
Nembutal has two problems for me: possible problems at the customs (although this is a matter of luck I suppose ...) And my difficulty to drink two bottles due to a big problem with the arcades associated with bad taste.
(My throat closes and I can not continue ... it's a strange thing).
The CO by itself (well done) should be enough. (A few bezos would also help).
But I am in the same case (without a suitable place).
The ideal to avoid failures and damage to others, would be in a tent in the field.
But the apparently simplest things are sometimes complicated.
As for the bag, it is assumed that it is not necessary to tighten it, even so, I would prefer not to use it. Although if I finally use the Amitriptyline method, I suppose I would have to do it.
It's a shame we can not get N powder.
Everything would be simpler.
