Other people have tried gum and not had it help them. I find it pretty helpful for me so far. I'm now two weeks in and I only chew 2 pieces a day now. Only have it when smelling others' cigarette smoke triggers my cravings. Overall, I'm gonna try to quit the gum by the end of next week.
I will note that I seem to have way easier of a time with nicotine withdrawal than other people I've talked to.
