First thing you need to understand is tobacco is one of the EASIEST one of the MOST DIFFICULT ADDICTION TO GIVE UP AT THE SAME TIME!! Its easy because quitting tobacco does not cause any significant side effect apart from some craving irritability. Difficult as we tend to continue tobacco thinking lets have one more before we quit. One way of quitting tobacco is decided a quit date usually 2 weeks from today start using nicotine replacement therapy available as Nicotine 2 4 mg chewing gums pastilles These are park chew type gums similar to your panini use 1 chewing-gum can last 2-3 hours. Gradually replace chain with these you shall get used to them. Additionally, you can visit a Psychiatrist get yourself Tablet Bupropion or Amitriptyline which reduce the craving for tobacco along with these chew-gums during this 2 week quit date period.
