As others have already said, don't smoke on an empty stomach. With that said, for the first 3 or 4 years of this hobby, the strongest cigars never got me sick, nor even a buzz. I could smoke full body cigars first thing in the morning before breakfast without any ill effects. About a year ago, my favorite full body cigars started to make me nauseated even after a full meal. I'd have to toss them half way through. It got to the point where I had to switch to light to medium light smokes. About 6 months ago, I started taking a quality, raw, whole food vitamin, and now I'm back to my full body cigars, and before breakfast smokes. Something to think about.
