I have had this cough for one year it appears to come and go.. sometimes in the morning I get it so bad, I start to gag and sometimes even throw up either what I ate for breakfast or just plain old white mucus comes out. I was recently sick on October 2nd.. with two ear infections and slept for four days straight.. went to Doc and was given amoxicillin for 10 days. to kill the ear infection.. I have been so busy lately after feeling better from taking the amoxicillian.. but this cough I have and have had for one year since last October. i went to Doc in January and February and was given cough syrup took about three bottles of it.. and the cough still has not disappeared... as of now.Today I did not have energy.. I slept...11 hours .. from last night to this morning and then laid down from 5 p.m. to 9 p.m. and slept more... I really want this cough to go away I do not know what it is.. I was shopping last night about 6:30 p.m. and was coughing in the store.. and someone asked me if I had been seen by Doctor for it. I said yes.. have had this cough for one year now.. too. I do not know what it is?
