Smoking cigs on 7oh

While this stuff is great and I luckily almost never experience much nausea, I've seen a good number of people speak very highly of nicotine while on it and I just wanted people to know that ymmv - I'll light a cig a good hour into the high, and before I can even finish it I get an overwhelming urge to throw up. This has happened countless times to me, I was just wondering if anyone else gets the same reaction often.
