When I come out of a sleep to get up - usually I get up before my alarms rings at 3:45 in the a.m., I can feel my heart pound in my chest and physically see and feel my left side of my body moving. No other physical symptoms - no flushing, dizzy, shortness of breathe or anything - just a pounding - then I get up and get ready and it is OK. So................? Could this just be an andrenaline rush from my bio-clock to get me up or what? I m 46, no other med problems - no maintance drugs, no alcohol, no drugs at all, no smoking , I do not feel stress from my job - love it.............all OK. SO..........?
