Lately I have been having a problem feeling like my heart is beating very iregular, but this only seems to occur at night when i m getting ready to go to bed. As soon as it gets to be about 9m or so, i strat to get ready for bed, same as usual, but as soon as i lay down I start feeling the heart palpitations. Its not painful but very bothersome and scary to me. I also have a weird feeling in my throught when this happens....anyone have similiar symptoms and if so, any clues to what might be wrong? also, i have been diagnosed with anxiety disorder when i was 7 ( i am 21) but dont feel lik this is the cause.
