I did some salvia for the first time recently. The first try I just took a little bit, and had did some pretty relaxing, smile-inducing daydreaming. Multicolored bears driving around in VW Bugs, that kinda thing. Pretty easy-going. I was using a water bong, and on my 2nd try (about 1/2 hour later) I took as much into my lungs as I possibly could muster. Well, it just knocked my brain right out of my head. I thought that I was out for hours, but I guess it was just minutes according to my GF. I was trying to lie down on the floor, and I could see the room arcing upward as if it were the room falling up and not me falling. Everything was changing shades of color, and I kept falling, resetting to sitting upright, then falling again; kind of like a typewriter or a broken record. That went on for what felt like a 1/2 hour. Then I hit the floor, and even though there were tons of blankets there and I just laid myself down, I had the feeling all over my body that the floor was pummelling me and compressing me. Then I just lost all sense of myself and had the distinct impression that the center of my consciousness was in the coffee table I was sitting in front of, and around which the whole room was rotating. The blankets on the floor were like some kind of thick, soupy substsance that I couldn't get off me. I pulled myself out of this imagery a few times, but was forcibly sucked back into it quickly in a way that I could feel through my body, like my body was being dissolved into the room around me. When it started to wear off, I just wanted to cry. I layed on the floor and did a lot of thinking about my life and whats important to me, as I tend to do when I'm high in general. All in all, taking the full dose was a mind-bending experience. It was draining, challenging, and completely overwhelming. I'm looking forward to doing it again and exploring the drug some more, but it's definitely not something I'd ever be willing to do lightly or casually.
Salvia isn't a recreational drug. Believe it or not, you've only just scratched the surface. Try smoking more and make sure you hold the smoke in for as long as you can for a true break through trip.
