One thing you might be able to do is try to lower your resting heart rate. Mine was around 80 for a while, but I started running and it dropped by about 10 beats per minute. I don't know what kind of shape you're in already, but you could try some cardio to get your heart in shape and your heart rate may not rise quite as much.

Another thing that helps is sleep :thumbsup: One time I was sitting at my desk hitting my vaporizer (one of the first couple times I had used it), and I felt like I was having a heart attack, so I went to bed. Same thing with the racing heart beat, if it's late, I usually just go to bed. Come to think of it I've had a few incidents like that with the vape. One time I got far, far too high..I was standing in my bathroom and suddenly the room got really, really dark. If you've ever played Call of Duty, it felt like what happens in the game when a grenade goes off by you and you get shell-shocked. I'm guessing it was the result of very low blood pressure due to vasodilation. Scared the shit out of me, but again, I just went to bed :stoned:
