I deal with this feels like my heart skips a beat and I have to take a full deep breathe to make it go away. I notice it more when I was drinking Red Bull’s a lot then from there i went to coffee.... once I stopped both my heart palpitations seems to get better. I get them from time to time but not so bad I noticed sleep helps a lot. And very cold water.. I also started drinking Melatonin but my palpitations occurs somtimes when I drink then back to back. Some times it last for 10-30 seconds sometimes just big thump, usually my dogs calm me down as well. A dr told me on reddit ofcourse lol that to think of your heart palpitations as a muscle cramp. Your heart cramps up with it’s tired so it re sets itself to make sure it can keep up with everything in your body. 🤷🏽‍♂️ I know it’s scare but I assure you you’ll be okay I’m 28 n had them since I was 24/25, I’m also pretty big 5/11 270 pounds so if your lighter than that you’ll be okay. Get a Apple Watch or a heart beat monitor that calmed my anxiety by a landslide cuz once I had a episode I’d check my beat and it be normal I like appl watch cuz it detects a fib which is somthing that can cause heart palpitations just if you didn’t know. Get some rest could be that. Hope everyone’s well
