Probably once or twice a year now. No longer on
metoprolol, switched to Bystolic some years ago.
Onset was after my aortic aneurysm grafting surgery when I was 46, I'm now 62 (16 years later). I'm retired, still very fit and active (6000 to 8000 miles of hard cycling per year, BMI 21). I've had two or three mild concussions since 2004 in cycling accidents, no impact on the white-outs.
