E.H.
My son is 5 & has always been the "puker" of the family & I now know why. For example, a few weeks ago for several nights in a row, he would say he was going to throw up, he would run to the bathroom & lean over the toilet to throw up but wouldn't. The dr prescribed Prevacid & anytime he feels like he's going to throw up, I give that to him & he is fine. Prevacid is pretty expensive though, I did "mail order" & it was much cheaper.
He also feels car sick sometimes, but I think he gets that from me!
