Your opening comment disturbs me:
"......and today I am going to try to quit smoking again......."
There's a reason you are using that word "again".
If you set out to "try to quit smoking" then that is what you will succede in doing - trying.
You won't succede in "quitting".
And you will be doing it - again.
Don't "try" - just "quit".
Attitude is the single most important factor in your success.
Accept the fact - in full 100% honesty - that smoking is your enemy. Every single pack you buy is only one step closer to poorer health and detriment to your life.
Believe it and accept it, because it's true.
When you buy what you want to be your last pack, forsee it and set up a particular time/date/etc. to buy your LAST PACK knowing full well that when that pack is gone, it will be your final pack.
When it's gone, you are DONE.
You QUIT.
You don't TRY.
You don't STOP. (If you STOP, you can just start agian!)
QUIT.
Quitting is not a ceasing of something. It's an ACTION. It's a DOING. It's something you actually DO.
It's not the ending of an activity, it's the beginning of a new activity.
The activity of a life FREE of that enemy that only wants you to DIE.
I watched my 69 year old father and my 57 year old brother DIE from throat cancer.
I smoked 2-3 packs of Camels every day for 30 years.
After sticking my father's ashes in the ground, it was evident what the results of smoking are.
I QUIT on his birthday so I would ALWAYS remember the reason why I made that choice.
That was 9 years ago and I HATE the smell of that enemy.
Don't dick around.
Get mad at what it is and what it is doing to you.
Pick a day that means something.
Buy that last pack. Smoke it. Enjoy it!
When it's gone, you're done.
Think it'll hurt a little? Yep.
Gonna be uncomfortable? Yep.
Gonna have some withdrawals? Yep.
So what. All of that goes away and goes away FAST if it's what you want.
Just friggin' quit and do something FOR yourself.
All of the gum and patches and pills, etc. are FUTILE if you don't truly want it for yourself.
In the end, it's YOU that quits.
