I have never seriously tried to quit cigarettes. Sounds like nicotine withdrawal and not having that the stress reliever of smoking cigarettes is probably a big factor as you say.

Good for you for not giving in. Its hard sometimes. I think for me cigarettes would be the hardest.

I think I have decided not to smoke pot anymore even if it was very infrequent. See my above posts. I have not had any cravings though.
