Lil, Ask your Dr for a prescription for Maxalon or Motilium... both of these contain Domperidone, which increases milk supply... they are also Anti Nausea medication, but thy increase milk... Motilium worked wonders for me... my milk suppy was huge, but you need to make sure you get loads of stimulation before coming off as they can decrease your supply slightly when you come off... so make Griffen feed loads or express more before getting off the medication.
