Yes, Domperidone take more time to work and it isn't instant relief as Reglan did, but it won't cause tardive dyskinesia. I'm starting to eat less if I get full easily due to slow emptying and overfeeding. Reglan is just like Thorazine that works fast, but Domperidone is just like Prozac that need take more time to be effective and side effects will be disappeared as body adjust to new medicine.
Reglan made me moving a lot and I had to stay in bed - messing with comforter, felt tremor and shaky. It went disappeared after I stopped Reglan and worried about could be diagnose with TD.
