I can't really speak with authority on smoking as I've never done it
I'm reasonably knowledgeable on fitness and diet though, and quite into exercise as I was painfully skinny not that long ago and hated it.
So if you need advice and/or motivation specifically about those topics, I'll do my best to help out!

Working out is really tough when you smoke. And all my male relatives does it. I want to stop this madness. My teeth is fucked up, I'm tired all the time etc... But my job is also a bit stressful so a cigarette comes in handy. I tried to stop before but I'm a weak ass. I HAVE to do it.

Right. Well you've already taken the first step, which is deciding that it's a problem - by your own judgement - and deciding that you can do something about it so good for you!

Chantix worked for me. I think the biggest thing is to be really ready to quit. I am a year and a half without smoking and I don't really miss it.
Yes I gained weight but a few extra pounds is nothing compared to what cigarettes do to your body.

i don't recommend going cold turkey, wein yourself off them, make a pack last 2 days, 3 days, and so on until it lasts a week, then 2 weeks, then only after meals (the hardest time), then only after dinner, after a month of only one a day after dinner. Stop, you'll still feel like a smoke a year later, but that's the mindset.

Also former smoker here. I stopped before I reached 1 a day.
It was easier to drop it but even after 3-4 year the smell of tobacco makes me want to go back.
Normally if you have friends that smoke you may want to distance yourself a bit. Don't replace it with an unhealthy eating habits.
Slow down. It will take a while but you can go from a pack a week to a pack a month. Then just schedule you smoke like only one in the morning and one on the afternoon.
Normally finding other hobbies like jogging or drawing may help.
Find something you live and keep your hands and mind busy.
Took months for me to stop but here I am.

I used Chantix nearly 12 years ago. It made me nauseous for 2 months, but I stuck it out and I have yet to have tobacco... Last one was Feb 7, 2009. I also put $5 in a jar each day (the cost of cigs back then) and watched it grow. If you have a setback, try again... I had to quit 5 or 6 times until it stuck. GOOD LUCK!

Also, you'll continue to emotionally crave tobacco for a good long time, but it could go away. About 5 years after quitting I realized I hadn't missed it in a few months. I didn't even know I could regain the mentality of a nonsmoker (as opposed to a former smoker). Hopefully you find that, too!

Chantix is the way to go but there are a couple of really big caveats. First, it’s going to suck really bad while you are on it. It blocks the nicotine so you keep smoking but you go through withdraws anyway. However, since there is nothing you can do about it you lose any desire to smoke since your body no longer gets any reward. Second and much more severe is that you can only do Chantix once. I quit for two years and tried it again and I lost track of what was a dream and what was reality so I had to stop using it. Once you are quit just remember if you take one drag you might as well buy a carton. The cravings are insidious so you have to be vigilant.

If you want to go down the slower road I would recommend switching to vaping over cutting down your smoking frequency. You will get immediate health benefits in the area of breathing. Then you can wean yourself off of that.

Thanks everyone.

Really helpful. I'll gradually stop and set an end date - 12 January 2021. Keep me in your prayers.

12 Jan? 2021? Such a short time man. Maybe put the end date a few more months down. How much do you smoke?

I never smoked a puff in my life but I can say that both my parents quit when I was very young and we have all been so happy that they did. We talk about it on occasion and about how worth it the decision was. They never stink of smoke, their health is far better, they don't pay out the nose for worthless cigarettes every day, it's win win for everyone involved. I think most importantly of all is that they taught me from a very young age that smoking is not worth it and will only make your life worse. I was pressured by friends to smoke throughout high school and never did. Just quit. It'll be tough but you'll be glad you did.

If it can help, I know someone who stopped completely overnight due to a health scare and she coughed like mad for 3 days and indeed put on some weight, yet in 6 months she was good and doesn't regret it.
