How many here "play" with their Rx drugs? An example: A year ago, I was taking drug "C" at 12.5mg - I then signed up to try the drug "Entresto" - didn't work for me a major dizzy (or was it vertigo?) event occurred. Next in line was "Metoprolol" @ 100mg. Gave that up recently. Back to "C" @ 3.125mg 2X daily - until I am "stable." What does "stable" mean? - Don't know yet. Maybe the dosage I was taking over a year ago would be more effective?
