I don't really like chewing gum. Once the taste of the gum wear off, I throw it out. But I guess if you consume about two packs a day, you also don't like it when the gum has no taste already. I know some people like to chew gum for hours even without its taste anymore. Anyway, there are bad side effects to chewing gum and I hope this helps you get rid of the habit. One is that it is full of sugar, essentially it can have bad effects on your teeth. Even the sugar free ones! It can cause dental erosion or cavities. Then, it makes you take more gas. Which can lead to GIT problems. Another one is that it can cause TMJ due to overuse of muscles. Good luck! I hope you get rid of the habit/addiction!
