Day 12 - when do thoughts of cigarettes go away?

I am reaching my week 2 of quitting after smoking 20 years, 2 packs a day in the second decade :/

I notice in the past 2-3 days my thoughts on smoking have increased. In the first week I was focusing on the physical symptoms and getting better, so I had very few cravings in moments of high stress. I even went out for coffee and beers several times with friends who smoke, I was not thinking about smoking at all.

Now I see that I miss smoking and it is in my mind many times during the day. I do not intend to light up, I am very clear that I will not get hooked on that shit again. But I was hoping that I could focus on other things and move on with my life, practically forgetting it exists as I approach week 2. I live in a country where you smell cigarette smoke everywhere so I will always be exposed to it daily.

I know this is is different for everyone but please tell me the thoughts do go away. Am I doing something wrong?
