 [ Symptoms ] i have vomited every night shift in a strange way starting to accept this vomiting as normal [ Disease ] in my opinion in your symptoms i do not find something that related to a cause of concern vomiting after a cough can be due to irritation of the gag reflex by dry coughing secondary to smoking i feel it is more related to stress or anxiety if no other symptoms associated then it is just stress if you have any other symptoms please let me know further we can try drinking warm fluids and see
