My uncle buys chewing gum in bulk, so he gets them cheaper, and it has stopped him smoking, he just has gum all the time and chews on them for a while.
When I had to quit stuff like that, I just went cold turkey, and I was fine. In my opinion, though, try to replace it with something productive, like working out.
I Heard That Instead Of Smoking sucking on a lemon or sumthing is better...i dunno if it true..u can try it....sour or smoke...??
what i found is to find something else to be addicted to i got off games for a while because i took up running
