i have refluxand it is often worse on cambridge due to nothing much going in my stomach. i take omeprazole which i get prescribed by the gp but ranitadine ( zantac ) works well too and wont knock you out of ketosis
one really bad night when i couldnt lay down because of the pain i took omprazole, ranitadine, gaviscon and tums and was kicked out of ketosis as tums has citric acid in it
with mine i feel a bad pain in the middle of my chest that spreads thru to my back and up my neck, can often taste the bile and am usually sick at the end of it all thou the vomiting doesnt usually occur with indegestion, usually is the pain
