I get this fluttering chest feeling when trying to sleep. i couldnt sleep all night, untill i was just exhausted and then finally slept. been happening past weeks. is this anxiety?i do have gerd, and on ppi daily?

Fluttering in your chest can be due to an arrhythmia, anxiety, too much caffeine, and several other causes. See a Dr in person and get a thorough examination to determine what is going on.

Try to reduce the amount of caffeinated drinks during the day, move last meal at least 2 h from bedtime, no alcohol, if applicable for few days. Your symptoms do suggest arrhythmia that triggers anxiety/panic. If symptoms persist in spite of lifestyle changes see you doc.

If you're adept at checking your pulse you can determine if you're experiencing arrhythmia' s if the heart rate is over 100 per minute and if the pulse is irregular. Either of these findings would necessitate a workup including a cardiac examination, EKG, wearing an outpatient Holter Monitor & checking thyroid status. Your MD or a cardiologist can advise you.
