Hello!
My daughter is on Zantac as well. She used to projectile vomit and scream while eating and after eating. We never had issues with just spitting up, it was always flying across the room! After being on the Zantac, she has not vomitted in MONTHS!!!!! She no longer cries while eating and sleeps sooooo much better...it was an absolute LIFE SAVER

It broke my heart to see her in so much pain before the medication so I was so thankful that there was something that would help her!
She was also very gassy and would scream when she would pass the gas. After trying everything that they suggested for the gas, the pedi finally prescribed Levsin drops. She was on them for 2 months and all is better...no more gas problems and no more Levsin.
I wish you lots of luck! Keep us posted on how your little one does
