Once I got something like that (10%) at the dentist…boy, that stuff knocked me out in a few minutes, that’s what I say I don’t remember exactly. But it was salty and bitter, so saline for sure.
Note: I was in so much pain she couldn’t touch me, despite the 10ml lido I got before. I don’t remember what it was, the 10% is my memory as well, but you can imagine all my muscles being flexed, and the other minute I am like cooked sphagetti.
