Jackie, you asked in a previous post what I felt like prior to going to the doctor. My symptoms won't fit everybody, but I know another person who shared my experience. You are tired and have very little ambition. I thought I needed more or better sleep. The kicker for me was shooting ground squirrels out at the ranch and packing up my gear with 40 pounds left. I didn't even feel like shooting. When I saw the heart doctor I was told I was a candidate to have a heart attack.
