Can anyone give me some tips on dealing with silent reflux?

[hopefulmum79]

Hi everyone. I've got a 3 month old ds. He has silent reflux and colic! The colic has died down but his reflux seems to be choking him and makes him scream every 90 minutes or so. It seems to have worsened the past few days. I've cut out dairy and it seems to have helped but i just don't know what to do about the crying. Tbh its driving me a bit crazy and my 4 year old has had enough! He also has Gaviscon from the doctor but its pretty useless- can anyone suggest anything they may have tried?
