I have been going down this very rabit hole. What I have come up with is this. Gonna get a roll of Gorilla tape, think good duct tape may work? Two short pieces of pipe that I will wrap a sock around each one. Place on either side of my throat, so it will pinch both arteries closed quickly. Then some thin but strong rope, like work boot laces, Then one large oven bag. Then I have a cheep cordless drill I will put both ends of the string inside and tighten down the chuck, Then simply Place the bag over my head, position the thin rope so it holds the bag in place, and over the short pipes on both sides of my throat, that are coverd with a sock on each one, then simply pull the trigger on the cordless drill.
I have a few items left to get, not much, then of course a few dry runs to make sure it all goes to plan, then even may take a few benadryl to take the edge off,. See how the dry runs go, and practice a few times on the leg thigh, then if all goes to plan, and I think its gonna, I will get a hotel room for a couple of days, leave a note on the night stand, cover my body with the blanket, and simply pull the trigger on the cordless drill. See how the dry runs go. make sure it all goes to plan.
