I couldn't take too much medication while I was expressing as I'm a very high risk of Breast Cancer and taking those medications can also increase your risk (only slightly for normal people - but it was too big a risk for me).

So I took fenugreek (helped a little bit) and the best thing I found - Aktivite! I found a recipe (I think on here somewhere) for an Aktivite milkshake. When I took that throughout the day - I got nearly twice as much milk!! Amazing stuff - and Australian made (and yummy!!!).

Good luck!
