Smoking faster gives you less nicotine, not more. You have to absorb it through the small blood vessels and this takes a lot longer than inhaling with cigarettes. I smoke slowly as to allow time for as mich nicotine as possible to be absorbed. If I smoked a high nic blend faster, I probably wouldn’t get as mich nocotine as a low nicotine blend.
That said, keep a bit of chocolate by you while smoking, and when you get the wrenches, take a bite. It’s your sugar running out, and a little boost of sugar will keep you in the game. Personally, to me, Nightcap is a moderate nic hit. Keep on smoking, you’ll eventually get some tolerance.
