I had a very stressful day today - I was full of worry all day. I finally decided to lay down on the couch and started to doze off. All of a sudden, it felt like my heart went bonkers! I sat up quickly - that didn't help, so I grabbed my glass of water and took 2 big sips and it stopped. I had no pain, no lightheadedness, but obviously I started to panic because I was on the verge of fall asleep and was rudely awakened! I've had palpitations for over 2 years now - I've been evaluated by the hospital, a cardiologist and my GP, all which say it's due to anxiety because I don't have any heart issues. But I still can't get it through my head that I'm fine. Has this happened to anyone before? I'm panicking about it....big time! Please help!!!!!
