You'll definitely learn the most from direct experience. Some past work with other psychedelics will be a good thing when you take that journey. Don't be too shocked if you return from your Aya trip only to find that your novel is in fact not finished at all! Psychedelics can have a massive impact on creative work.

We've got at least a few other writers on board here. I've published books but it's all instructional material for artists. There's a thread in music/art/literature discussing psychedelic novels- perhaps you too belong on that list.

Welcome, glad to have you here!
