THIS MAY SOUND STRANGE, BUT I DO THIS RITUAL TO GET A HIGH NOW DAILY. I BEND OVER AS FAR AS I CAN, BREATH DEEPLY INTO A PAPER BAG A FEW TIMES, THEN I STAND UP VERY FAST AND STRETCH OUT MY ARMS. SOMETIMES I BLACK OUT BUT THE RUSH I GET IS TRULY EUPHORIC. I MEAN IT FEELS EXTREMELY GOOD, AND I DON'T KNOW WHY. HAS ANYONE EVER HEARD OF THIS, OR KNOW ANYTHING ABOUT WHAT IS HAPPENING TO ME AND WHY I GET SUCH A WONDERFUL FEELING FROM IT?? I THINK MAYBE IT COULD BE DANGEROUS, BUT I AM NOT SURE...THANKS FOR YOUR HELP...
