I started taking them a couple days ago, a very low dose just to feel it out. I feel my heart getting slower, and that freaks me out and makes me think death is imminent. I also get a bit dizzy. 

I can find nothing online for magnesium *causing* anxiety, only relieving it. 

Because the symptoms is gives me make me feel anxious, I’m scared to up the dose to the recommended minimum. 

What’s your guys’ experience?
