Welcome to HealingWell, and I am glad you found us. I am sorry but I do not have an answer for you re the cough. I have not heard that you would have a cough from switching meds which makes me suspect the cough is from something else.
Members with GERD often have a cough. However you did not mention that you cough at night but only when you wake up until bedtime. Please do talk this through with your physician or see a specialist if you have a history of asthma.
Also wanted to mention you have your caps on and this makes for hard reading for some people ........fyi and thank you.
Again Welcome to our great forum,
