Whenever I do any more than a bump or 2 of cocaine, my resting heartrate skyrockets from like 90 to 150. When I move around, I've seen it go as high as 180-190, and that's just walking to the bathroom. I feel like I might have a heart attack/cardiac arrest any second if I'm not sitting completely still.

I don't understand how others can just do a line or 2, and then run around and do shit. ESPECIALLY when mixed with alcohol; any tiny bit of cocaethylene makes me feel like I'm dying.

Maybe I have a heart condition or something, but I've gotten tested for almost everything and have never had any issues, so I have no idea. Am I doing something wrong?

(I take Adderall for ADHD but that hardly affects my heart rate. It's really just cocaine that's this bad)
