Phenobarbital or opiates for suicide?

Basically the above. I wonder what would be the most painless way to go? I know the in Switzerland they use Barbiturates for euthanasia but that shit is basically impossible to get over here in Kangaroo land.

I want to leave an intact body not some bloody pulp that an unfortunate soul will stumble upon.
