Thing is, Nicotine will stay in your system for 3 days. Stop both for 3 days. Anything after that, tell yourself you're a pussy if you can't stop. It's all mental after 3 days. After 5 months, start dipping again if you feel the need to. You most likely won't though. Stay busy doing stuff and you'll forget about smoking.
If the nicotine never leaves your system, there will always be a physical addiction.
