I used a patch the last time I quit (seven months ago now) which really took the edge off. I had tried to quit cold turkey before, but my family wanted to sell me to pig farmers because I was such a jerk. I've known folks who had better luck with the e-cigarette, gum, or lozenges. Others do well just putting the darn pack down. So, you've got to find what works for you.
Regardless of how you quit, get ready for the mental battle. You've really got to want this. When the craving hits, acknowledge it. Think, this is a craving. It will pass. I want to throw the towel in and have a smoke, but I don't smoke anymore and I am giving myself the gift of health. I am freeing myself from cigarettes. I will give it another five minutes. I will give it another half hour.
Take it a minute/hour/day/week at a time. Just put off picking up.
Find ways to take care of yourself that will fill in the gap. I smoked to get some time to myself, away from my kids. I smoked to stave off anger, sadness, and fear. I'd think, "What's wrong? Oh, I need a cigarette." Really, the cigs didn't fix anything, but it gave me a way to escape from my reality. I smoked because there are a lot of stressors and big things happening in my life and it felt like self care. I'm trying to figure out different ways to give myself that care. A bath. A cup of tea.
I'm a guy who always needs a fidget. Smoking gave me something to do with my hands and mouth. Gum, toothpicks, a ring to twist, a piece of yarn - didn't really matter what it was - but it helped to have something to mess with.
I was taking an anatomy and physiology class while I quit smoking. It was fantastic. We all know that smoking is bad for us. Go and find out how. Find out the nitty details of what happens to each of a smoker's body systems.
Give yourself pep talks. Know it really is THAT hard - so you don't need to feel insane or get down on yourself when you can't figure out why it is that you feel so crazy. It's a hard addiction to kick. A really hard one. So be nice to yourself. Give yourself a break if you are not quite yourself. It does get better.
There will be times when it gets a whole lot easier. For me, the first three days were the hardest. The next seven were almost as hard. Then it started to get easier.
To know, you might find that at certain anniversaries you are freaking out for a cigarette. Three months, six months, a year, 18 months. Get ready for those. Don't give in.
The farther you get from your last smoke, you might find it's harder to remember why you quit in the first place. Your mind might start playing tricks. It might say, "Oh, I didn't feel that bad. Oh, I quit then, so I could do it again, I'll just smoke for a little longer." It will never get easier to quit. We don't become less addicted. There's no good time to quit. No matter what, life will still be waiting for us, and stuff will get in our way. But, smoking doesn't actually fix any of it.
Get yourself a gift every so often. A pair of running shoes. A massage. A night out with the girls...take care of you.
And you may want to avoid the things/places/people who you associate with smoking. I know that if I had hung out in the smokers pit, for example, I would have picked up again. I had to take space from certain friends because it was too hard to not smoke with them. For some folks, maybe that's not so much an issue. For me, it was.
I wish you (and me!) luck. Be strong!
