Kathie I am not a doctor, or even a PWP, but I am 54, and a few months ago I started taking 2 DHEA pills every morning. I feel more energetic, and get by on about 5 1/2 hours of sleep a night, work from 8 to 5, and even have been doing some heavy cleaning and other work a few nights a week. Before the DHEA, I was falling asleep at the computer most nights about 10 PM. I hope it helps Ken B.
