Sometimes at night time like when I lay down &amp; wanna fall asleep, I feel like my heart is racing a bit or it just feels like it’s pounding harder. Can feel it in my back if laying on my back or in chest while laying. I just had a full cardiologist check up recently like ultrasound of heart, stress test, 2 week hollter monitor. All normal. It just drives me crazy sometimes especially when I’m trying to sleep ugh. I am a anxious restless person like 24/7 of my life. 

Anybody else?
