breastfeeding and trying to lose weight?

I had the sleeve 2 years ago, and just gave birth to my son 12 weeks ago. I am exclusively breastfeeding/pumping.  I eat all the time because I am hungry all the time. I still have 20 pounds of baby weight to lose, plus would really like to lose 25 more because I was not to GOAL when I got pregnant. So my question is for those of you who have breastfed, how do you lose weight? Everything I read says dont crash diet and keep your calories at 2000 in order to maintain milk supply. HELP! :)

Keep me updated on what you find out!  I will be in the same boat as soon as my little girl in born in a few weeks and I have been wondering the same thing.  How much weight came off right after having your little one?
