I have found on occasion, that if I smoked a larger cigar too fast(over a year since it happened), even though I don't inhale, I would get pretty sick from the nicotine overdose. Empty Stomach was usually the culprit, but I found that if I ete a bit, then took my time, and really enjoyed the cigar as it was meant to be, I was fine....much worse nicotine rush than my first 'dip'. First time it happened, I was clueless.
With some cigars, I have to give it a bit of a French Inhale to get a few more of the taste notes, or let the smoke go to the back of my throat to make it go through my nose.
The Drew Estate 'Nectar' Ambrosia was one such smoke. Very strong clove so it almost demanded more creative measures, and toying with to enjoy the smoke's note. That sucker took me right back to the old 80's clubs with the DayGLo Girls, and their clove cigarettes(Oh man those were some days!)
