I prefer gum, and I think patches are ideal without the gastrointestinal upset.
What dose do you think nicotine should be maintained at to attenuate lipolysis and "acclimate" the organism to its effects. It has a very short half-life, and I'm feeling ideal at very low doses (.5 mg or so).
Also, there's evidence that lipolysis brought on by nicotine does not trigger through adrenaline, but rather pro-oxidative means.

I'm still researching dosages for nicotine. I think niacinamide and nicotine would have fantastic synergy and should be taken together. It seems likely that any negative effects nicotine may have will be eliminated with the right dosage of niacinamide. Niacinamide inhibits lipolysis, encourages glucose oxidation, inhibits cancer metastasis, inhibits nitric oxide etc... Also every dose of nicotine should be taken with a decent amount of carbs or a meal beforehand. I would experiment with varying doses of niacinamide from 100mg-1000mg with every dose of nicotine. Aspirin may also increase the synergy- you could add 80-325mg aspirin to the mix and see how that goes. I would probaly just keep taking the low doses if it feels right and be consistent with taking it everyday. I would treat nicotine similar to how I treat caffeine.
