Hi. My mother has had two heart attacks. The first one was a few years back and the other one was a little over a year ago. She has stopped taking medication, can hardly breath, smokes two packs of cigarettes a day, her diet sucks, and she sleeps a lot. She is 59 years old. Her father died of a heart attack at the age of 57. I m afraid we will lose her. Is sleeping a lot a sign of the end? Please help.
