Welcome to our community!
I am sorry I missed your earlier posts....must have been asleep on the "job." Here is my usual welcome for the newly quit. Lots of good information linked here for you. The more you read about this addiction, the better able you will be to beat it.
To answer your question, I think the first few days - two weeks were the most difficult of my quit. You re challenging many years of habit and association, plus the physical withdrawals. The quicker you decide that you will not smoke again NO MATTER WHAT, and understand that what you think smoking does FOR you is a lie, the easier it will be.
The most important thing you can do right now is to educate yourself on what nicotine does to your body and mind. To that end, I highly recommend Allen Carr's “The Easy Way to Quit Smoking.” This is an easy and entertaining read. You can buy it online, or get it from your local library.
You should also read the posts here and perhaps go to the pages of folks who you think might be helpful. You might visit whyquit.com, quitsmokingonline.com and livewell.com for the good information contained there. @https://excommunity.becomeanex.org/groups/best-of-ex has lots of blogs written by members of this site with their experiences and guidance.
The idea is to change up your routines so the smoking associations are reduced. Drink your coffee with your OTHER hand. If you always had that first smoke with your coffee, try putting your tennies on right out of bed, going for a quick walk, then taking your shower and THEN your coffee! Rearrange the furniture in the areas you used to smoke so the view is different. Buy your gas at a different station. Take a different route to work. Take a quick walk at break time where the smokers AREN'T.
You need to distract yourself through any craves. You can take a bite out of a lemon (yup - rind and all), put your head in the freezer and take a deep breath of cold air, do a few jumping jacks, go for a brisk walk or march in place, play a computer game. Don't let that smoking thought rattle around in your brain unchallenged. Sometimes you need to quit a minute or an hour at a time. You will need to be disciplined in the early days to distract yourself when a crave hits. Get busy! Here is a link to a list of things to do instead of smoke if you need some fresh ideas:

The conversation in your head in response to the "I want a cigarette" thought needs to be, "Well, since I have decided not to do that anymore, what shall I do instead for the three minutes this crave will last?" Then DO it. You will need to put some effort into this in the early days, but it gets easier and easier to do.
