I suffered from this for four years- there was a six-week period I was able to stop but I wen back to it. I finally, finally was able to kick the habit almost a year ago but it had such a hold on me and only got worse with time. I chewed and spit every day, any chance I could and otherwise are healthy! Always alone. But it was so mentally unhealthy and it showed that I had such an unhealthy relationship with food. Since I quit, I gained a bit of weight but as I lose it, I feel pure knowing I am doing it honestly, through fitness and health. I encourage y'all to get help- it's not going to get better, only worse. And, ugh, now I need a root canal and I know exactly why!
