Dear Tom,
Its nice to know that you have tried to quit.
I am a non-smoker so no personal experience. I am lucky to not have tried the first fatal drag.
But we all are passive smokers, not to mention the pollution around.
I have helped a friend to leave his addiction to smoking. It took him more than 6 months but he did quit it. Being a Reiki channel helps
I tried the following method......
Sent Healing to the situation where he smoked the first time.
Every ailment has a emotional side & cause. In Chain Smoking the reason is Denial of Self & Inferiority. So I had to address this situation.
Later when I attuned him, I advised him to do do self healing in the same way.
Used Affirmation & Visualization. One should Imagine a blank screen. Now draw a picture of you smoking. see the harm you cause to self & others. Now send Reiki to this picture. Slowly visualize Reiki wiping away this picture & replacing a picture where you are in harmony with the surroundings. Do this 2 times a week & Reduce the frequency of this technique & in about 3 months don't use it at all. After 3 months only visualize yourself in perfect harmony with the surrounding breathing fresh air. Bless this situation with Reiki.
The Affirmation I used for him was.... I Breathe only Clean & Fresh Air. He continues this Affirmation to date.
I also used a technique called Mind to Mind Healing which uses Affirmation & Reiki symbols. This had to be done several times hands on in person.
On the physical level I advised him to reduce it gradually with the last phase of smoking only 4 times per day till he leaves it permanently where his higher self tells him smoking is useless. Also advised him to buy the costliest available brand during this phase.
I hope this helps you. Tell me if I can be of any further assistance.
God Bless.
