Ive been having trouble finding the sweet spot too
I think I found it once by following my adams apple, I think I still can sometimes, but they say it doesnt take much pressure and I havent been able to get much of a reaction from it so Im not even sure thats the right place
It sucks because I was pretty sure that was going to be my method
I dont have the exact resources but Im sure I could find something to replace the bags, and I do have tape
I wish you luck, I wish it was easier to find for you
And if you do find the right spot I hope its a peaceful journey
You deserve to be at peace, you do, and to be free of suffering
