My toddler son has had reflux for a little over a year now. They currently have him on Prevacid in morning, Reglan three times a day, and Zantac before bed. He also seems to be very hyperactive. Did anyone else experience this with Reglan. I have stopped the Reglan (for reasons that don't have anything to do with this) but how long will it take for the Reglan to be completely out of his system?
