Welcome, Hev!! I'm not familiar with what tabex is, is it some form of nicotine?
I don't envy you living where smoking is the norm (boy would I have said otherwise five and 1/4 years ago!), here in the US it is more and more difficult to find a place to smoke without some sort of restraints or constraints, besides being looked at like you are the devil incarnate if someone sees you smoking anywhere within their airspace. So that makes it easier here .
But the effects of smoking are just as harsh on you who live where smokes are cheap and smoking is the norm, you don't get a free pass from smoking related diseases, so you are doing the best possible thing you can for yourself, as well as for your loved ones.
I smoked for a very long time also. I honestly thought they would have to pry my last cigarette out of my cold dead hand.... but here I am and couldn't be more pleased with the decision I made and the effort I put into freeing myself from the chains of this awful addiction!!
You're doing great, and taking one day at a time you can make this journey to the point where it is no longer a struggle. I know the first two weeks are the hardest, and there is no "instantly easier" point that I recall, but very soon you will look back and say "Yeah, today was way easier than two weeks ago was.... still not easy, but less difficult than then". Then you'll begin to have some golden moments and golden days where time goes by without even thinking about cigarettes.
Keep on with what you're doing, because you're doing it right! NOPE one day at a time, and sometimes one hour at a time, and that will get you where you want to be!
Best wishes to you!
