oh it all sounds so horrible even thinking about poison. My reason for asking was wondering how available it would be to get hold of. In the instances of these peoples case.
The thing is, if for instance I had been in their shoes, i would have got hold of whatever it was, via online or somehow, - bet is is quite possible, and then done it at home. Nobody else would have been implicated, and for the family I can think it would be no worse whether they were in swtzerland or at home (that bit to whollyGhost)
If there was another option, i really don't think i would go abroad in order that i can DIY. Yes, if someone was going to inject me, where there would obviously be implications over here, but a self administered OD , with a written and witnessed will, I think it would be much better.
