Its fun man. 2c-e is like taking acid and E, but putting like a magnifying glass on the acid portion. So instead of getting lost, it's like you have super powers! I always see colors I never knew existed before. But personally, I like doing it around my house because then I can zone out and listen to music of my choice, or draw/write. It's great to go out hiking, so I have a large park nearby that I walk through at sunset if I do it then.
Whatever you do, just be chill and have the options open so that everything is available. I think the hardest thing is to find stuff to do when you're like 3-4 hours in and your body has kind of adjusted to the high, so you're a little "sober" in the sense that you can command yourself more. And you start thinking "oh shit, my time is running out. What else do I wanna experience?" but the body high is so intense that you don't give a fuck anymore.
