I used to smoke pot and drink all the time. One day while smoking, i had an intense panic attack, Everything was completely normal at first, the usual high..Light body, cartoon vision, ya know..and then my heart started to beat tremendously fast and all i could hear was it beating...my hands started to tingle and then it shot throughout my body. So i sat down and tried to relax but it got worse and i felt like i was going to die..i wanted to go to the hospital, everything around me was going slower than usual and all i could hear is the clock, odly, we had slipknot blasting..But it was the worst experiance in my life..a couple weeks later i drank with my friends and then my face started to tingle and that rush of panic came back to me and i had to curl up on the bed and i couldnt move..and the same thing happened until i fell asleep. the next day when i thought i was fine it happened again, while i was SOBER. And i continued to have panic attacks randomly througout the day for a whole entire year. I also got heart palputations. I feel so scarred now because of it. Sometimes i wish i could smoke again, but im so scared to do it agian because i dont want the panic attacks to come back. It has been two or so years since the event. Does anyone know what went wrong with me, or know of a way to stop it in the future?
