Smh must be a bug going around Im sick now since last thurs feel kinda better tho! Get soup & crackers, halls, caffeine free tea I use peppermint tea..orange juice, ginger ale & im takin Robitussin dm
No suggestions, just know what your going thru. I've got the cough that doesn't really want to leave, it has caused me to nearly throw up a few times, so thankful I was able to keep stuff down. I've ended up on a new inhaler because of it, shortly before finding out I was pregnant.
The robitussin dm will probably help the cough, if it sticks around for you may want to check with your doctor.
For a deep chest cough i would try some Vick's vapor rub on your chest area & something that will also soothe the back of your throat too.. laying down i heard can make the phlegm worse so maybe prop up on some pillows??
