what happened?

I think the same thing that happenend to chris happened to me. i had smoked about an hour and a half before, i remember thinking that i was going to pass out thought that i had shaken it. i was standing talking to my girlfriend and started feeling it again so i sat down and it kept coming i knew i was going out and i told them i was going to pass out. first my vision started fading and when it went totally black i couldnt hear. they said i was out for about 2 mins. I thought that i was going to die. then i came back to conciousness and was very dissorinted and could not shake the feeling that i was going to pass out again about half hour later it broke and i went into a cold sweat and my body temp was 96 degrees i still felt like it was going to happen again until i went to sleep. ihave passed out before and knew it was happening but it never lasted this long. Could it be that i was thinking about it kept the feeling with me? ZANE
