Suggest Treatment For Headache And Tiredness

I have been feel overly tired and have seen doctors and had routine blood work done they all tell me its life, I eat a very healthy diet and take vitamins everyday, I also suffer from headaches in which I take Fioricet for. Even though my blood work says I'm fine..my tiredness is cronic! I go to bed between 9-10pm and wake up at 6, there is no reason I should feel as though I cannot function from the moment I wake up until I go back to bed. Please help!
