I have been smoking for 43 years and have stopped and started for so long now. I can't seem to go longer than 30 days before I relapse. I am getting close to the end of this disease. And don't want to stay on oxygen like they say. Im afraid that I won't ever come off. I just got diagnosised with colon cancer and have to have cancer on the 13th of next month. I started taking chantix and have one more smoke day. I could use any support or advice. I know I must be crazy because why would I do something that I know is killing me.
