Acid reflux

Who's little one has acid reflux?? My son is 7wks old and is batteling severe acid reflux.. I am strictly breastfeeding and he spits up after every feeding and sometimes during.. He was on medication but it didn't work so his doctor took him off it.. Sometimes he can't keep any of the milk down and he gets soo angry.. Does any one else deal with acid reflux this bad if so what is something I can try to make him feel better?? I hate seeing him in pain..
