Chronic cough

I have had a cough for about 2 weeks now. I started out coughing in the morining some during the day and at night each time it was a "productive" cough mostly clear and whitish colored phlegm. This past 4 days have not been good at all.  I sleep about 2-3 hours then wake up haking with a barking cough with nothing coming up 3 nights in a row I have vomited from coughing so much. Also, during the last four days coughing has gotten a lot worst throughout the day with the barking cough. I was taking OTC mucus relief pills and allergy meds plus a cough suppressant but that did not work. Yesterday I took none of these except for in the morning and the cough has become less barking with more mucus production so I am thinking maybe I should stop taking the meds.  Problem being I still have to go to work and deal with this coughing its becoming embarassing.  My husband is about to loose it with me getting up all the time at night.  I am 27 years old I used to smoke but have quit could this be lung cancer or COPD symptoms? My ribs are hurting from the cough. I need sleep and I need to get back to normal. Any suggestions?

Try taking a sip of liquid Benadryl. If an allergy is irritating your throat, this will work.
