Almost every night as I'm dozing off , right before I fall asleep I get this kick in my chest , like I'm forgetting to breathe or something . It's scaring me pretty bad . It'll do it multiple times before I finally fall asleep , and every time I sit up quickly and gasp for a breath . It feels like my heart stops . I've told the doctors and they say they have no clue what it could be . Besides something anxiety related . I just left the ER with a normal ekg , normal blood work . (Heart enzymes were all fine) . Good results on urine tests , etc . It's really getting old , and I feel like every night is my last when this starts to happen . Anyone ?
