Acid Reflux constant screaming

Wifey • Mama of 1 ... ttc #2 Rainbow Baby with secondary infertility.
Anyone else dealing with acid reflux or similar symptoms? My son is one month old and after feeding (most of the time) he screams bloody murder for a long time and it's so hard to calm him down. I feel like he is rarely ever just content...he is either eating, sleeping or screaming. 
Doctor has him on a light prescription and we are putting cereal in his milk to make it thicker so he doesn't spit up so much. But I am losing my sanity!! 
Anyone else in a similar situation? Found anything that helps or just able to show me I'm not alone??
