What does not being addicted feel like?

People who aren’t addicted to smoking or drinking or any intoxicant, what does it feel like? Im addicted to nicotine, been crushing vapes since 3 years. I wanna quit, just can’t gather the courage to do it. I miss when I wasn’t fucking addicted to vaping and nicotine. Im so passionate about CrossFit and fitness. Smoking just makes it so bad.
