For some reason, the Dr. upped it to 5mg every day, and I felt my riding performance suffered.
When I went back to every other day, I rode well again.
That dosage seemed to work well back then.
But, now I have read that Norvasc eases the burden on the heart, lowering pulse and giving increased exercise capacity.
Dunno what to believe................
Not much history of heart disease in my family,,,maybe maternal grandfather.
He had several heart attacks in his later years, but was not athletic in the slightest.
High BP, on the other hand, is a different story.........
