I had three hits last weekend (first time with salvia was last weekend) of some 15x salvia. I doubt I did it right completely though, just because I couldn't hold it in. Someone was lighting the bowl, and just kept it lit forever, and unless I was gonna take in more than a lungful, I didn't really understand how it was gonna work, and had to keep it in my lungs for over 20 seconds, (Maybe 10 seconds most when I did it, after I was down on the bong for like 10-20 seconds already). First bowl was weird, like some reason there was like a drape over the window in the shape of an M, and it stood out so much that I started pointing to it like with FORCE. And then when I finally let out, I yell SUPER MARIO, IT'S THE SUPER MARIO M!! And then I went to check myself in the bathroom, and I was in another world. After that, I took two more hits, and I couldn't really move. I don't know if I couldn't, didn't want to, or just didn't. It was a really dream like experience, like being super super high. It's nothing great, but worth trying if you just have to know what it's like.
