Coughing til I puke??

Dee
Seriously going through the worst cold I've ever had. I'm coughing so bad my sides hurt and it's made me vomit three times. Has anybody's cough affected their gag reflex or do guys think it's something worse?? (I don't Have the kind of doctor I could just call and ask). Also what do you guys do for colds when we can't really take anything?
