Only advise is the same for drugs and alcohol. You have to want to stop enough to actually stop. Then, you also have to remove the temptation. This means no smokes in the house, no visiting places where smoking is the norm < bars, taverns, etc>. It also means not associating with friends who are smokers, a hard thing to do is to give up friends.
An alcoholic can't have beer and liquor hanging around the house, go visit his buddies at the pub, he has to remove temptation to "cure" himself. This may mean you have to remove your significant other, or get him on the same no smoking kick.. then you are both support for the other.
Remove the things that make you want to smoke, stress, or fiddling with your fingers, etc.
Good luck, my parents and wife quit by going cold turkey, they found that easier then patches, gums, and other pseudo solutions, but you need to do what works for you.
