Yes!!! Barb, the doc at Mayo said I MUST have been woken by something — a bad (or good) dream, hubby snoring, or whatever. *eyeroll* Dr. McDonnell showed holter monitors on us that showed how we spiked at night time — and it wasn’t rare at all. In fact, our average heart rates were often higher at NIGHT TIME than in the day time. THAT is NOT NORMAL. After antihistamine treatment and mast cell stabilizers, that symptom stopped for me, for years!!! But now that I have a torn rotator cuff, fibrosis, etc, it is coming back. This is not good!!
