Hey, I'm 59. don't look or feel it. but recently (last several months) I get very tired during day and feel need to take naps... sometimes up to 1 and 1/2 hrs. Then tired and sleepy again by 9 p.m.... usually resist and the feeling goes away. Normally sleep about 8 hrs per night.... and though tired, often have to take a sleeping pill to fall asleep. Have been taking lipitor and zolof for several years. other than getting swept away with this sudden fatigue, I'm in very good health. I think it's a lack of regular exercise... but don't know.
