Reglan or Domperidone? Tried everything else! 😢

C
Does anyone have experience with either reglan or Domperidone? 
My lo is almost 5 weeks and my milk supply is next to nonexistent. It came in late after my csection (for breach). I've tried everything - consultants, all the herbs, teas, skin to skin, nursing vacation, pumping, power pumping, cookies, oatmeal, Brewers yeast, Guinness, etc., etc. I still can't pump much more than 3 oz a day and I've only managed to fully feed (without a formula top up) by breast milk twice. 
I'm at the end of my rope with all this stuff waiting for the magical day I pump even a full ounce at one time. I was thinking about asking my ob about Reglan or Domperidone at my next visit. Any thoughts? Are the risks worth it?
