I first did it yesterday, and smoked it with a little bit of weed. I felt like I was shrinking. I'll try it again by itself. I started with 5x, because I'd never done it before and it just seemed safer.
I know that some people don't really feel the Salvia unless they smoke it with weed. I don't know if that's just the way they are, or if they're doing it wrong, or what.
