Tatiana, over a few years prior to actually quitting I had tried to ween myself away. Unsuccessful, when it came time...I went cold turkey. I will say that no-one wanted to be near me for a while, but in the end I think it actually made it easier. Every time I thought of smoking, I would look back at that short slice of hell and it was enough that I did not want to go through it again! LOL, I know that sounds sort of simplistic...but it worked!
We smoke for different reasons. Some do it to relax away stress, like taking a five minute breather in the midst of things. I found once it was no longer there to provide that, I did have to find something to replace it. I would get up from my desk and walk a few laps in the hall of the building and then go back to work. This covered the habit that was the break smoking allowed for me. The withdrawals...and that is certainly what they were had to sort themselves out through time.
You got this! Just know that. YOU have the power here to let it go when you are ready and you will know that moment. There are plenty of aids to help, gum, patches, spinners and such. I have watched them work for others very effectively. For me though, I was on a crash course with transition and that was one of the big initial bumps...thought it best to hit it head on 🙂
