I did. At around 10 months in I realized that my visuals and intrusive thoughts increased temporarily every time I smoked cigarettes or electronic cigarettes (especially the first cigarette of the day). So I quit and it`s almost 4 months now. In the past 4 months I had the most progress. I`m sure clean eating, exercise, healthy sleeping habits, and staying away from drugs helped as well. In the first 7 months it seemed like smoking did not make it worse though.
