Funny, I was addicted to nicotine for around 10 years. I got tired of smelling like smoke and I became really tired of the taste. Decided to quit one day and just stopped and have no desire to go back. It was incredibly easy. That was around 20 years ago. Caffeine/Tea/Coffee I am fiendishly and hopelessly addicted to; having tried numerous times to quit or cut back intake and I always fail.
