I took 3 ambien on the 14 hour flight back, had a
six pack of beer with the guys, and went to sleep. The next day I woke up, drank an energy drink (which I have been drinking at the rate of one to two a day for the past 2 years) and suddenly had a really tachy heart beat and a faint radial pulse. I went to the ER and the ECG came back normal. Over the next month I had 5 more ECG's, 2 blood tests for thyroid irregularities, a chest X-ray, a 24-hour Holter monitor, an MRI, and a stress test.
