Milk supply?

Mariah
This isn't my first child but with my first I got really sick after I came back from the hospital and couldn't eat anything to produce enough milk for my baby so I had to give her formula she is now 2 btw. But I want to breastfeed with this one I'm hoping I don't get sick after this one but I want to know is there anything I can drink/take that will help me produce enough milk?
