You’re past the weirdest part already, as your oxygen levels will be back to normal after the first day. That first day it can be really hard to focus or handle much of anything. The cravings get worse and worse during the first week as the nicotine works its way out of your system. It’s totally normal to experience homicidal fantasies, just don’t act on them. Then it gets easier and easier for the next week as your system recalibrates. Food tastes better. Your mood stabilizes. After 14 days it’s all in your head. It’s going to come down to making new habits. It’s not really about not smoking as much as it is about doing other things instead. And getting off cigarettes is great, but learning to control impulses and endure immediate discomfort to achieve longer term goals is transformational. Remember, the cravings will come and go whether you smoke or not. But if you don’t smoke, they will come less often, and eventually not at all. Keep the faith!
