It worked a bit for me, but when I took a high enough dose to make more milk I stank of it in my sweat (def NOT maple syrup!).
I'm taking domperidone (prescribed by my gp 30mg 3x/day), and this really does work. I wish I'd taken it earlier, my supply then may have been enough to ebf, as it is, I started it at 6 weeks and now combi feed about 50:50 formula and bf.
