"I try my best to be extremely disciplined about my diet." — Mika Brzezinski

I realize that of all people, I am no expert on parenting or marriage.

I am up at 3:30, reading the op-ed pages and getting ready to be on the air by 6 A.M. on the set of 'Morning Joe,' and after three hours of TV and two hours on the radio, it is only 12 noon.

I suffered from a mild case of postpartum depression after my second child and the physical challenge of maintaining an overnight shift at CBS, a marriage, and two in diapers made the symptoms worse and everyone in the house paid the price.

I am a marathon worker and marathon mother. I'll spend three or four days completely swallowed up by work. And if I make it home in time to say good night, I may have one good hour with the girls, maybe a brief family dinner or a family walk with the dog, and then it is back on the computer to prepare for tomorrow's shows.
