Yes, the first 2-3 weeks are somewhat miserable for each of us. Don't magnify it. Look at it like a bad head cold, It's frustrating to be sick with anything.
Turn it around. Instead of blaming this misery on your quit, blame it on smoking.
It will get easier and easier if you stick with it.
Keep unlearning the hand to mouth. You have to break that thought pattern of reaching for a cigarette.
Continue to change things up. Small changes that keep you aware you are doing something positive will get you through.
As smokers we never even knew we were controlled. As you're quit goes on and you distance yourself from smoking I promise you will see it.
Onward to FREEDOM!
