I quit CIGARETTES five years ago (quit drinking at about the same time).

I used Chantix for the deterrence effect it has (only side effect was really bizzare surreal dreams).

I vaped for the hand to mouth habit.

I chewed nicotine gum for the strictly mouth habit and needing something to do (chewing gum helped with fidgets).

I ended up chewing the nicotine gum for all of these 5 years until 3 weeks ago.

Right now I am feeling the quitting of the gum: depressed, tired, irritable, unmotivated, can't talk right, clumsy, etc, etc, etc, etc -- what's funny is that

I didn't put two and two together until today that I was feeling these because of the nicotine withdrawal. I thought I was just I had swing into depression on some unknown trigger.

I haven't really craved nicotine, until today just after lunch -- before that I was always fidgety and would get up and walk around at work, etc....

So it's possible -- just remember that smokes and gum and all that other jazz is TOTALLY WASTED MONEY -- that's partly how I quit -- I came to realize that smoking/drinking didn't get me ANYTHING -- there was nothing obtained by paying to do these things -- so I quit...or worked to quit, cuz it was work for both.

Good luck -- eye on the prize, one minute at a time -- and keep in mind craving last no longer 5 minutes if you can distract yourself when you feel them -- like I am in writing this .
