I had thought about doing this, I abandoned the idea a couple of years ago, and I'm starting to think about it again. But like most things, my opinion on it changes frequently. Most days I think that doing it would be so difficult as to not be worth trying. But on other days I think that I should at least give it a shot. I know for a fact I won't be able to CTB soon. So why not save money, book a flight, and at least give it a try? The depression I've experienced has been fucking brutal. I feel like, at the very least, I deserve a dignified death after having such an undignified life.
I speak Spanish well enough to get by. I wouldn't physically pass off as a local in any of the countries listed in PPEH, but I would be able to converse with them. I'm sure the vendors are more sympathetic to older visitors who want to buy N, but I don't know how willing they'd be to sell it someone younger. I'd have to make up a plausible story.
One thing's for certain. I would not bring it back with me. I would take it wherever I purchased it. This is something that is a big part of why I'm hesitant. I know my family would have to go through the trouble of bringing my body back or traveling to bury it there. My relationship with them is poor and many of my issues stem from my upbringing. So, perhaps it would just be karma.
