Well, at first we thought fruit juice was the culprit but cutting it out didn’t reduce the urps.  So now we’re back on meds – 15 mg of Prevacid daily (and can I just say – OUCH – because Prevacid is a top-tier drug).  They seem to be keeping the urps from being painful – Shoshanna hasn’t been acting like she’s in pain (and she says that her throat doesn’t hurt) but she’s definitely still bringing food partway up after every meal, so we’re working on limiting her meal size and spacing out when she eats better.
