my wife has taken codeine based cough syrup along with the strong antibiotic augmentin. her doctor warned about taking other cough medicine, that there might be a reaction.. she began to act out of character about an hour later, really emotional, wanting me to leave her alone, she wanted to sit in the dark in an extra bedroom. she said leave me alone, I've taken 3 gel nyquil, and i just want to be left alone. could there be some drug reaction from taking the nyquil with the codeine based cough syrup?
