I get acid reflux up to 3 times a day, You dont feel hungry, it's like heart burn or indegestion. When i was a baby i had projectile vomit cause of it. Thats right i could spew and hit someone standing 6 to 8 feet away from whoever was holding me. But as for being hungery after you eat, it might be your motablizm, as that also happens to me. My grandmother always said I "ate too fast." This can happen where your stomic thinks its full cause too mutch food enters it at once, then well theres not as mutch food as it though. When i try eating slower, i knotice i dont get hungry as fast and it help with reflux and the like. Hope this helps
