While I quit smoking over two years ago - I cannot say I have not cheated once or twice. All you can do is get through today without one and then when you do, try the same thing tomorrow. Only those of us who have been through the hell of this cancer and still pick up a cigarette and smoke one can understand. The couple of times I smoked a cig - I felt horrible and was scared to death my husband would find out....ridiculous for an adult! All you can do is move forward -you'll get through this - we're all here to help you!
