Is there a list of cryonicist-approved suicide methods?

I recall a conversation somewhere which considered the options of a hypothetical terminally ill patient who wished to cryopreserve himself before his brain was further damaged. Finding a country that allows euthanasia and having a cryo team on site seems like the best option!

Failing that I expect drowning in a partially frozen water source (with an observer nearby to secure the body) is probably a reasonably good option. Don't shoot yourself in the head or jump off a cliff.

Oh, I just noticed you are the same user who was casually ambivalent about the suicide option in another comment somewhere about here. That changes the connotation from pure theory somewhat towards practical advice seeking. I probably should clam up now and play the signalling game!
