K.W.
I have been taking domperidone (called motilium overseas where I order it from for much less $$ than you can get it here) for over a year. I took up to 160 mg a day at one point, but now that my baby is over a year I am taking just 30, and she's still nursing happily. I have had no real side effects, and neither have my kids (as far as I can tell). It works like a charm for me--I've had a full milk supply for both of my adopted kids. But I know it doesn't work that well for everyone. Fenugreek is also great. Good luck!
