I took Reglan - I think it helped my supply. Certainly didn't hurt or lower my supply after I took it for about 3 weeks. I have a history of depression, so my midwives were wary of prescribing Reglan for me (LC suggested it), but I had no problems. (Of course, I did all the other stuff too - pumping, oatmeal, beer, breast compressions, Fenugreek, Blessed Thistle...)
