I guess the question is, are you talking about the immediate aftertaste, or the next day dragon breath that inevitably comes after a night of cigars? If you're having issues with the immediate aftertaste of the cigar, you're either smoking shitty cigars (of which there's nothing to be ashamed of) or you may have eaten something before smoking that is causing a disagreement on the tongue. Try changing up what you eat before you smoke, or smoking something different.
If you're talking about the next day funk, make sure you brush before bed and first thing when you get up. Another thing that I've found really helps is to floss, too. I hate flossing, but I've really been making the effort to floss every night and I've found it really cuts down on the after-cigar morning breath.
And welcome from MT.
