Reflux

ami
My baby is breastfed, and is having reflux trouble.  He doesn't puke, but he is constantly trying to clear his throat.  He can't sleep - he stays half awake barking/coughing/gurgling all the time.  
Anyone else dealing with this or have advice? 
I've got him on a sleep ramp, and am trying a paci to get him to swallow (but he's too new at it to hold it in his mouth while sleeping).
