I'm going to talk to him about my heart. I've been having these random episodes at night where my heart just starts racing and pounding. That's why I couldn't sleep last night. My pdoc thinks it's just anxiety, but there's no trigger, it just happens randomly. But my thoughts aren't racing, I'm not worried about anything. And I've tried everything, meditation, deep breathing, music, distraction, cutting out caffeine, avoiding scary/energizing tv shows or books or music before bed, reading until I get sleepy, melatonin, benadryl. Nothing helps. And then of course I get worried something is wrong with my heart and that doesn't help.
