hi my name is anonymous, i am 21 years old, am 85 kilograms and 1.75m tall, i am on no medication, i am a vegeterian-for 3 months now, i have no chronic ailments and am fit and in good shape although i smoke cigarettes, i have recently been on a health binge to purge my system of toxins,(no drinking or narcotics). Yesterday i was out with friends celebrating my friends birthday, i drank whiskey-3/4 of a bottle, tequila-1 shot, 2 beers, i then proceeded with my friends to get pizza at a corner store, i ordered a pizza then went outside and asked a friend for a drag of his cigarette( it turned out later that it was a substance called mr nice guy), i took a puff then went back inside, i began speaking to a friend, then everything began to slow down in my mind, my speech slowed to point of me not being able to speak, i turned to the pizza man and then blackness, with a feeling of euphoria and utter terror mixed into one, which felt like 3 seconds, i then woke up on a chair surrounded by my friends telling me that it is going to be ok, apparently what had happened is that the pizza man saw all colour disappear from my face, i stopped speaking and stared at a fixed point, i was completely unresponsive, my heart was moving at an abnormal pace, i then fainted, but my eyes remained open the whole time, my friends then put me on a chair and i was unresponsive for 20 minutes in real time, but in my mind only 3 seconds had passed, i then regained consciousness and began to speak slowly, i felt completely sapped of energy as if i had been drained, i could not speak and was unable to focus on anything. It was the scariest thing that has ever happened to me, i managed to walk home and pass out but, today i have an incredible headache. My question is this, how did i faint with my eyes open? why did there seem to be so short a time in my head and yet i lose 20 minutes of my life? and finally, what damage have i done to my mind? please help me
