Discussions that mention xanax

Can tachardia only present itself in the middle of the night, i.e. about 2 hours after falling asleep? Because this has been my problem for a few years now. I awake out of sleep to a pounding heart rate of about 115 bpm and blood pressure which rises when this happens. I have no other symptoms like pain in the chest....only some nervousness and the feeling of being very hot when this happens. (Not sweating, just very warm.) I get relief from 2.5 mg of xanax or a little piece of valium. When this first started went to my GP - he did an EKG - said it was tachardia (spell check) and said otherwise I was okay. I have been episode free for about 3 months now when all of a sudden the rapid heart beat awakening me came back this week. During the day I am totally fine. Can someone identify with this. The elevated heart rate can last from 30 minutes to a few hours and then it disappears just as it came.
Thanks for your input.
