You feel better because the Coreg blocks the adrenaline.  Now that you have stopped it your adrenaline is flowing making you feel great (like you can do anything).  The question is what is your blood pressure now?  If it is high, this will overwork your heart and hurt your heart muscle.  Stopping Coreg can send a person into heart failure.  Usually, it will happen within a 3 week period.  You need to let your doctor know that you have stopped the Coreg.  Coreg has the side effect of making people feel tired, but people who really need the Coreg are helped by it.
