Maintaining a healthy diet while breastfeeding

Crystal
How do you maintain a healthy diet? I have the best intentions everyday, but it's so hard when I'm always hungry. I used to eat pretty well prior to my pregnancy, but after I gave birth all I seem to do is eat whatever I can find, or pick something up out if convince. I never knew I would drop back to my prepregnancy weight, only to gain it back. Any advice, tips, resources?
