I know it's gross, unhealthy, a stupid habit, makes no sense.
Trouble quitting cuz it's something to do with hands, fidgety, restless, oral fixation I think, and it gets me out of the house. Can't find a habit to replace it with.
I used Nicotine patches and would use dip patches on occasion, as well as eating a lot of cough drops while I was quiting. Not sure how good eating cough drops was but it worked better than candy for the oral fixation.
It took me too many years to finally quit the habit from when I determined that I was going to, but I am very glad that I did. Good luck, I am rooting for you.
