Forgot to mention in my last post that approximately 25 years ago I was diagnosed with Supraventricular Tachycardia (rapid heartbeat). Was put on beta blockers and also calcium channel blockers and took those for 15 or so years.
I decided in the end that I would like to give them up so went to the hospital and saw a heart specialist who said they did not believe I had this condition and from my notes had ever suffered from it.

Now, what have those tablets done to me over those years. Maybe nothing or maybe I have yet to see.
