Oh, yeah -- Almost forgot to mention: If you are ever in the hospital for cardiac reasons and they give you immediate medication for your heart (as opposed to long-term meds), expect to get the worst headache of your life as your cranial blood vessels dilate along with the cardiac ones. Note that the beta-blockers were developed for cardiac conditions and are now used also for migraine prevention. We have our own internal "ecology" and you can't mess with one part w/o affecting others...
