Swanny raises a good point. I did assume you meant you were smoking and drinking at the same time. Like having a cigar (while) enjoying a dram or two. Is that correct? Or are you saying that after having smoked a cigar - you don't find your whisky to be as peated say the following day?
Any rate I often hear people recommend power-house cigars against power-house whiskies. It's been my experience that this is not necessarily the formula for a match made in heaven.
I'm by far no expert on this or any subject, so please take my comments to be that of my experience and mere opinion and not that of a clinical expert.
1) I'd identify what it is you are trying to experience. In that are you trying to find a cigar that compliments your whisky more so than a whisky that compliments your cigar? Which one is more important to you - the cigar's taste or the whisky's?
2) With both, as mentioned, I'd try to identify those that compliment each other as opposed to conflict.
As is the case with life in general, as you experiment you are likely to run into way more conflicts than compliments on your journey. Don't give up. . . Then again if you are quitting a habbit, maybe "Don't give up" is a poor choice of words on my part!
