Am I doing this wrong?

Hello! Very new to this. I can’t debilitating heart palpitations, now while I’m not counting on CBD oil to fix that, I was hoping it would take some of the edge off the anxiety I get surrounding them.

This is what I purchased: https://www.greenroadsworld.com/products/cbd-hemp-oil-100mg/

I’ve taken 1ML (one dropper full) once for the past 3 days, but I feel absolutely no different whatsoever. Does this mean CBD will just not work for me? I’ve heard so many success stories I’m super bummed
