Do You Know Who I Am?

I'm dark brown in color, and sometimes white, I'm terribly desireable, and very well liked, By those who love me, they crave me too, If only you knew me, you'd feel that way too. I'm enjoyed by both men, and women alike, But in me is where women, find their true delight. Have you guessed who I am? Do you at least have a clue? Shall I talk a bit further? Yes, let me do that for you. Now I'm not all that good, I'm sometimes bad, To the very one's who love me, I deliberately make sad. To over indulge may bring strife, I can bring true havick, into your life. I stand alone, and take all the blame, Do you know me now? Have you guessed my name? If you don't know me by now, and still can't guess, It's time to put your mind to rest. I Am C H O C O L A T E !
