Pre-light, I don't do anything. During, I always drink something and for some reason it has to be more than water to break up the taste of the cigar and refresh my palate (coffee, iced tea, but mainly alcohol - beer, wine, whiskey or rum. The one thing I don't drink before or during are pales, IPA's and DIPA's. I love them and drink them probably more than anything else, but the bitterness doesn't go well with any cigar (for me).
