I am a newbie to pipe smoking, and I know this from personal experience.Applicable to both neophytes to the pipe and cigar, particularly those who are also neophytes to tobacco use: nicotine can sneak up on you.....to keep the sweats from developing into spins - or worse.
My first time experiencing any nicotine was my initial outing with my Legend corn cob pipe, and some Price Albert. Smoked it fast (causing tongue bite), and got a case of massive sweats, upset stomach, and icky ashen taste in my mouth. Felt like I was going to pass out, and don't know how I avoided vomiting!!
Had a very similar experience about a week ago smoking back to back King Edward and Dutch Masters cigars. Smoked them incredibly fast, and got quite sick (sweats, head racing, feeling that I was going to throw up).
Slow, and steady is a much better way to go!!
