I've been feeling strange sensations in my heart, especially when I get home after work, and at first I thought it was from drinking too much coffee. I've cut down on coffee but the feeling is still there. I do drink 2 coffees and 4 cups of tea every day. I also exercise regularly, like doing push-ups and lifting weights. Should I be worried about these symptoms? Could it be linked to my caffeine intake, or might there be something else going on?

stop taking excess tea and coffee
