Are you uncomfortable with flying, I mean worry about crashing? You problem could be anxiety driven. That's my first guess, and yes there are prescription medications for anxiety, I don't know specifics as I do not have that problem myself. Good thing I have well over 1 million miles of flying time in just on my main airline.
Are you on any medications? Some can cause dream problems, and that could stimulate some of the symptoms you describe. Or, again, anxiety could be the driver even when sleeping, or trying to sleep.
Thanks Jerry,
No,I have been flying since childhood, but this problem started just 3 months back and i am not worrying about crashing also. Yes anxiety could be the cause, i was going through some tough situation in life and I was completely awake in the night, the day before I flew to my native. I consulted one physian yesterday, he suggested me to stop smoking and excess tea/coffee.He prescribed ambulax (In India this is the trade name, not sure about other countries, its prepration is diazipam+propanlol). So i started using this medicine. Lets see if it could help.
Good luck, sounds like you are on the path to better heart health.
could be anxiety, I fly a lot and used to occasionally get a claustrophobic feeling which triggers the anxiety and then the palpitations. anti-anxiety meds stopped that and it has not been a problem for a while.
