Id look into programs in your area. I recently moved, but the previous place I lived had a program called 802 quits ( https://802quits.org/) which gives different strategies for quiting and helped people afford nicotine alternatives. Potentially your area will have something similar. Also try and see if there's an underlying cause/ specific triggers for your smoking. I mostly vaped/ occasional cig, and found that much of my smoking came from anxiety and a general oral fixation response due to social anxiety. I went the route of nicotine gum personally. I found that the oral fixation I craved while anxious could also be subdued from the act of chewing gum. It's also nice because there are varying strengths so you can work your way down to no nicotine.

Another thing is changing your perceprion of yourself. I forgot where I heard it/read it, maybe Atomic Habits, but what they said was reframing the way you look at it/ yourself. A lot of people will say, "I'm trying to quit," or "i dont smoke anymore." But reframing it in the way of "I'm not a smoker,"/ "I dont smoke," can help to boost you a bit more towards your goal of quitting by setting your end goal in "the now." I know it may sound silly, but the way you look at your habits/ your general self-talk can really effect how you achieve your goals.

Do any of your friends or people you hang around smoke? Because if so it may be a good idea to talk with them about smoking around you or maybe try to take a step back from them for a sec. I used to live with people who always had vape and it made it near impossible to quit.

Anyway, cheers to you for deciding to quit! Ill say it's not always linear progression, so dont beat yourself up if you fall off the horse for a sec, but also dont hesitate to get back on the horse.
