newbie, I have been at varying doses of the domperidone. I followed Dr. Newman's guidelines for starting, found at
Domperidone, Getting Started Domperidone, Getting Started , starting with 30mg 3 times a day. I gradually worked my way up peaking at 160mg/day. When I no longer needed to supplement with formula I started to wean down my dose, and had been at 90 mg/day for a few months before trying to drop lower recently. Right now 80 mg/day seems to be working, so I will stick with that for the next few months, then re-evaluate.
