I have seen a couple of posts where someone has said they were a failure....
That is "stinkin' thinkin'" my friends. You did not fail.
The only way you will fail in this journey is if you just plain give up and stop trying to quit smoking! Are you willing to get up, dust yourself off, and begin the journey once again?
Then you are not a failure!!
You suffered a slip in thinking because of the addiction to nicotine.
Ol' Nic is a strong character. He is also a conniving a$$ that will do anything to keep you in his clutches.
Fill your quit toolbox with the weapons you need to reject Nic's lure and hold.
Use gum, hard candies, cut straws, a lemon, put your head in the freezer or anything you can think of to kill the crave.
This journey cannot be made in one day. If it could Nic wouldn't have any prisoners to his poison.
A journey is a series of steps that take you somewhere.
The same with your quit journey.
Take things one second, one minute, one hour, one day at a time.
You will get to the other side of NML that way.
I know you can do it!!
Ask for help when you need it and I will promise that people here will do their best to help.
One step, and the another, will get you where you want to be.
