I know you can wean off the dom and I bet it's different for everyone as far as maintaining your milk supply. I would do it very slowly and gradually and be prepared to start again if your supply suffers. Also, I just read an article on this site that suggests that the breasts respond to high blood levels of prolactin when the breasts are empty, so I infer that it is good to take the Dom/herbs while I am pumping so that by the time the meds kick in I have empty breats ready to respond to the higher prolactin levels. MORE MILK! Hope it works.
