Welcome to HealthcareMagic.First of all, if you are addicted to something and want to quit, that too, without medications, you need to have strong will power to do away with it. Depending upon type of craving you have, like post meal a fag, you can replace very well with a gum/ friut.If it is accompanied by a drink, try drinking in places where smoking is prohibited. Then there are Acupuncture
, behavior therapy, hypnosis
etc which are seen to have played its role apart from medications like non nicotine
.Wish you all the best.
