Suggest Ways To Reduce High Cholesterol Levels

I have changed my life style due to high cholesterol which were in the 800 range and Triglisterids which were over 1000. I now have them under control. And excersize daily. I sleep fairly well at night. But every day I yawn, all the time. Like every 5 to 10 min. But don t feel tried. Do u recommend anything that can help with this?
