After using ecstasy/mdma for at least 2 weeks straight. The last time i did i had very weird chest pains. Thought i was going to die. I said I wouldn t ever do it again but after 2-3 days the slight numbness went away and about a week later i did a little bid of mdma. For the first few hours it was good. Then I started feeling the chest pains and the numbness in my left arm. Pretty much everything symptom i read online related to a heart attack. And the more I remembered what i read. Those feelings showed up. r So im not sure how much of this is happening to me. Or how much of it is in my head. The first time I went to the emergency room they told me my heart rate was fast put me on iv for a few hrs and sent me home. With papers on drug abuse. But never specifically mentioned it was a panic attack. They did say it wasn t a heart atack though. So please help me out with a little information on this? Possibly tell me what i can do to slow my heart rate when on it and after it.Im definitely going to slow the using of it down alot. But in case i do use it in the future I would like to know what im in for.
