I've been struggling with this for about 2 months now, i have a serious case of bad breath ever since i stopped smoking 2 months ago. I thought cutting back on smoking would help but it has actually gotten worse, my sinuses also feel worse like the is more mucus than ever in my throat. I always have to be clearing my throat ever 2 minutes regardless of what medicine or gargle solution i use. Please help me as it is tremendously affecting my social life which has been great up till now.
