You have to get your liver enzymes checked at least once a year to make sure the
tylenol isn't damaging your live.There are people dieing from this so take it seriously.Also Darvocet (propoxyphene) is a very poor pain killer and you could get just as much releif from
advil,you should try and stay away from it.Also don't drink to much or take benzo's when taking prop[oxyphene as it can cause respitory failure.....Dave
