Yep, it's happened to me before! The night that I broke up with my gf of 2.5yrs, I smoked a little over an eighth of fire dank in one sitting while watching Eternal Sunshine of the Spotless Mind alternating between a blunt, a bowl, and a bong (Jack the Ripper). I was a little hazy as if I'd just woken up from a nap, and I felt kinda numb...mentally and physically BUT I was totally sober! It was crazy. Before that I'd heard rumors that it was possible, but I never really believed it til then.
