Need to absolutely listen to your body. Your system expects that 81mg aspirin. As Slick pointed out, things can go sideways fast.
My mom has had 3 heart attacks in less than 3 years…first natural, other two due to getting off her blood thinners for minor procedures. Otherwise, she’s sane and healthy, EF is 55% resting…better than all her kids. Frying bacon for breakfast the day after she got out the hospital after the last one Easter Sunday. Don’t ask her age, it will just bum you out, but she’s got us all covered on this board.
