yeah it was a wild experience, cuz I felt the blade cutting me, but I was like, surely just my mind playing games, then I started going into shock (according to the nurse) I was white and could-sweating so they upped the dose and still felt most of it, I usually felt pain at the dentist too, then I started mentioning that I have issues with the "standard" numbing agent because I forgot the name and since then going to the dentist is a breeze, get the stuff, get numb, stuff is done.
