Sleep help

I know many of you have mastered the art of sleeping. I love to sleep and as mentioned yesterday, love my sheets, but for the life of me - I can not sleep past 6:30 no matter how tired I am, what I have to do the next day or how late I went to bed. I need your tactics. I have tried them all. Then about 2:30 in the afternon I can't function anymore. I am also slightly anemic (or so I have heard) so this doesnt help the situation.
Charlsie, I know you can feel like an expert here....what do you have?
