Breastmilk supply

Are there any medications to help increase milk supply? Currently taking legendairymilk supps n occasional 2nutguys nut butter. Not too keen in fenugreek or lactation bakes/teas. I'm an extremely picky eater due to some childhood eating issues so would very much prefer medication of any sort. Anyone tried domperidone? Where n how can I get it? i'm borderline undersupply at the moment n my 5mo's appetite is getting bigger n bigger, soon I will be very undersupplied.. Also I'm already supplementing FM once a day, hoping to stick to pure BM only like with my first..#advicepls
