help, milk supply down! (Domperidone)

pls share your experience with me on Domperidone. I have my own (non adopted) baby, but can not find many people on Domperidone to ask. I was using 6 x 10 mg/day to BF my 6 mo.old baby, things were going pretty well. I tried to reduce the dose (as suggested by Dr Newman) by dropping a pill. This resulted in a dramatic drop in milk production! I am in total panic! (By using a scale bf/af I am at 60% of production). I am now taking 6 pills again, but I see no change yet after 3 days. My baby is hungry and I have to supplement with formula to stop her screaming... Does anybody recognise this? Can I repair this, and how? What is your dose and how long are you taking it? please help, I am afraid this is the end of BF for us. Z
