Hmm, I knew most people had bad salvia experiences (heck, my own ranged from neutral to terrifying), but you seem to have had an extremely averse reaction to it. Even though my last trip was the terrifying one, and I haven't done it since, I've not sworn it off either. Ah well, to each their own. Just know that you aren't alone, most people who try salvia don't go back to it. I had my friend record my third trip, the terrible one. I wish I could get it off my phone, because it's actually rather funny. Especially the point where I mumble to the camera, "kjsdfalkjhdfs....THESPIRITS...safkja"
I didn't think it was all that bad. I've done it three times, and each trip was actually quite enjoyable. I didn't mind it at all!
Fuck man, you can't give up on it till you break through at least once, you'll either love or hate yourself for it.
