After reading Gwern's writings on nicotine some years back, I did a bit of research myself. I can't recall where I read this, but I did come across some anecdotal datum about a person using nicotine to help them workout. However, that person was quite strict about their usage. He or she would only using nicotine when working out but never any other time. The reasoning was that nicotine helps in habit formation while active in one's system. So, hopefully the brain would crave working out because it would associate the reward of nicotine with working out. I do not know how it turned out, but I thought that was an interesting idea. What if nicotine could be used to aid in forming healthy habits, and once the habits are established, nicotine could be weened out? Do you think nicotine has any kind of similar effects for you?
