Quit date is Sept. 22. I am doing it cold turkey. Is it possible? Has anyone done it? I have tried so many times. I have been smoking for 20 years. The last time I tried to quit I tried Wellbutrin and I became manic. Chantix made me suicidal. I can't afford Patches or nicotine gum. So I am scared that I am not going to be able to handle the withdrawal. Please help. Thanks.
