struggling with heart palpations

for 2 weeks or more now... idk why... My blood pressure is ok. i think it’s because i’m dehydrated or lack of calcium ... it’s an awful feeling, it’s scary .... what should i do or buy for them to stop ???? i also cut offf alcohol too because i heard that was due to it ... i also don’t drink any black soda AT ALLL. Just water lemonades and juices.
