Re: Got really sick
Hajo and Pigpen hit most of the big points - too much smoke, too short of amount of time. Nakhla has more nicotine than many other brands, plus big clouds means you are getting LARGE doses of both CO and Nicotine. Neither is good in large doses - even if you are a major ciggy smoker.
Plus, it sounds like you may want to reconsider the brand of Quicklights your using - coals can make or break a good smoke.
Slow down, taste the smoke more than play with the clouds. Eat and drink something before and maybe during as well. Relax and enjoy, take breaks and if smoking with other, let than have more time. You may gain a tolerance to the Nicotine (if that was the main issue) after some time, but the CO you won't.
