no, i didn't take anything...i did quite a few different things to induce them though, including writing my dreams down extensively. at first i could only remember one or two flashes of a dream and jot down a few notes (some nights i didn't remember any), but after 3 or 4 weeks i got to the point where i'd remember multiple scenes from up to 10 or 12 dreams in one night, writing up to 20 pages at times.
i also did something where i'd sort of act out or role play a script created from a combination of my written down dreams. i'd take the original notes and dream stories and fragments, and re-create them into a story or script, and then ultimately, in my waking life, i'd act the dream out. if it involved people i knew, i sometimes asked them to participate. the results of these experiments surprised me, and twisted things in ways hard for me to describe without writing one of the stories here.
anyway, i did several other things like this, mixing dreaming and waking life through various exercises in a couple of books on lucid dreaming that i read, and altering a few for my own tastes.
regarding taking something, I've taken a few things over the years and enjoyed mushrooms mostly, although i didn't involve those during the lucid dreaming stuff. also, i vape weed a decent amount, and i like what it does for me creatively, and i guess i could say, surreally.
edited to add.....that i only got to the point of lucid dreaming a couple of times - meaning i had awareness of my dream state and could alter (somewhat) the course of my dreams. but what came out of the process more than lucid dreaming, was my ability to connect to things happening without my physical presence. again, another story would probably illustrate better, but i hesitate to write a short story in the comments just because of the length - this one seems pretty long already. :)
