You know those giant 5 gallon buckets of sunflower seeds you can get at Sams....yeah, I've gone through two of them. Sunflower seeds at home and gum at work. My main motivation is my twins. When my son (5 months old at the time) reached out to grab a water bottle I had been spitting in I figured it was time to give it up. It's definitely not a habit I want to pass on and I do not want to expose them to it.
