Not sure my milk is healthy enough?

Ok, i'm a new mom, my baby is two weeks old and this will probably be the one in one million questions i will ask on yahoo answers cause there really are some decent ppl out there willing to share advice. Anyways, like i said my son is two weeks old and since i've brought him home i haven't been eating all that well. I eat a little something for breakfast and then i usually don't eat again until dinner. I do get fluids in like tea and milk but not as much as i should be. I also smoke but i smoke outside away from the house and i do not smoke right before i feed or pump. To be honest i actually put my baby on formula for the time being until i speak to the pediatrician about how healthy my milk is. Anyways, when i smoke i smoke probably 11 cigarettes a day because i don't always smoke a whole cig at a time. Are there any other moms that feel the same way or do the same as i do? FYI i ALWAYS wash my hands and arms at least before i handle my child..no sarcasm please!
