Ok, let's address these triggers as I see it:

Being alone: You have us now so stick close, there's usually someone here around the clock.

Friends that smoke: Smokers hate losing one of their own that's why they're more than happy to give you that relapse cigarette. You will get to the point that you can be around them but it's best to distance yourself from them in the beginning of your quit.

Long car rides: This is where your air cigarette comes n handy. Some use cut straws, pens, even licorice to mimic a cigarette. Mine was invisible so I never had to worry about forgetting it somewhere. It's important that when you use it you go through the motions of 'smoking' it just like you would a real cigarette. It worked great at tricking my mind into thinking it was getting the real thing.

The after-workout- cigarette: Bring yourself a healthy snack instead. You can't eat and smoke at the same time

Phone calls: Again try using your air cigarette or talk somewhere that you normally don't smoke

Sex: Air cigarette again or sucking on candy

Food related triggers: Air cigarette or sucking on a piece of candy. I was stuck on soft peppermint puffs my whole first year.

I hope some of these clues help you out, you can do this, after all you've done it before

Thank you Jillar! Your air cigarette is quite famous by now.. I've seen it on the forum a couple of times, so I will give it a go!
 

Oh jumping in...

Friends.....I quit in the middle of softball season....lots of me softball mates are smokers...I couldn't avoid them...I will confess to doing the 2nd hand smoking thing but I would have 1 wiff then be off....see I knew I couldn't avoid it, so quick sniff opposite side of the dugout....my rules were simple, I'd allow myself to smell it but I was not having a puff ...it only took a few weeks and U didn't even want that smell hit. But I prooved to myself I could do it.

Post workout.....expanding on Jill's healthy snack suggestion...carrot or celery sticks...you can air smoke them AND have a nice crunchy chewy snack.

In my early quit I had a phone app...it had a crave buster feature...this was that card flip memory game....ran for 3mins on repeat...only once did I need to go back to back to beat a crave ..see your brain can't focus on a crave when you are making it do something else. Minesweeper worked too. 

You are going to go through a year of craves getting milder and also seasonal triggers.

Each trigger you conquer will change your brain and wrench your reward system away from nicotine.

The biochemistry of this is astounding and once you reclaim these receptors, they are Yours forever ! 

They will only return to nicotine if you do so, NOPE your way through.

This is why rewards are so important.

You are doing so great, have a super attitude and are ruthless in Sticks/Chicks !
