I stopped completely for six weeks (from when DD2 was three weeks till she was nine weeks) and had not a drop. I relactated to the point where I could get 60ml. But you already have some so it should certainly be doable. I expressed every hour for two weeks, took Motilium, took fenugreek and used a supply line. But, like I say, that was from not having a drop - much easier to do if you're already starting with some supply.
