finally he went to a hypnotist and he quit and has stayed quit for over 10-15 years.

I quit cold turkey a 3 pack a day habit in 1976
.
I helped a boyfriend quit a 30 year habit by giving him an herbal formula called herbpharm avena licorice compound (tincture). It is organic which means several times more potency than conventional herbs and in the best form that one should take herbs in ..a tincture (not capsules)

he told me he had no cravings at all for 5 days and he did quit.

The lobelia in it is used for tobacco and opium addictions.

The formula is Indicated in the treatment of tobacco (nicotine) addiction. Lessens the desire for nicotine, supports the nervous system and the adrenal glands, and has a cleansing and restorative action on the lungs and bronchi.

I was shocked as I had constant cravings when I quit smoking especially the first week.

I would tried this first as it is a lot cheaper.

I am sorry I can’t give you more details on the hypnotherapy. I only know this is how he quit but not the details but do try this formula that is specific for quitting smoking.

Many more tips on alternative health and quitting smoking are given in the wonderful reference book on all ills called healthy healing by Linda Page available at healthyhealing,com or on amazon no doubt.

And use it as part of a round of treatment. I’ve linked to an Ohio State study that talks about how effective hypnosis is for quitting smoking. Conclusion? It’s effective, but it gets used with other treatments so much it’s hard to say how effective it is as a standalone. I’m like, why wonder? Go ahead and use three treatments at once and quit smoking for good.

What’s it like? You’ll meet the hypnotherapist and she’ll explain what will happen. There will be a pre-talk, where you discuss your goals and she’ll explain how hypnosis works (by speaking to your unconscious mind to build new habits). Then you’ll go through an induction. That’s just a fancy word for a relaxation technique. Once you’re relaxed, the hypnotist will lead you through suggestions that will remove from you the desire to smoke. Some hypnotherapists make a tape of the session, or give you a stop-smoking tape to listen to in the coming weeks. By listening to the tape every day, you make sure the session sticks. And usually there’s a follow-up session at the very least. You could just buy a stop smoking CD online. The only thing is, they’re cheaper and people usually don’t listen to them enough for it to take effect. An in-person hypnosis session has a lot more power than a CD.

Is it pricey? It depends on how you do the math. A hypnotherapist might cost from $100 for a one-hour session, and might offer a one- or two-session treatment. So, about $200 to quit smoking? Walgreens has nicotine patches at $50 for a two-week kit… in a ten-week program. So that’s $250 to quit. How much is a year’s worth of cigarettes?

In fact, being pricey can HELP you quit smoking. It means you take quitting seriously enough to pony up a lot of money in one session. Hypnosis works with your subconscious mind. When the subconscious sees that money change hands, it’s like, "oh crap this is serious!"

Best to you as you try to quit!

Usually the hypnotist uses deep relaxation to bypass the critical factor of the conscious mind. The unconscious mind is very smart and ingenious. It pumps our blood, regulates our digestion and hormones, etc. even when we are sleeping. It is also a storehouse of thousands of memories our conscious mind has forgotten. Moreover, the unconscious is much more open to positive suggestions and can override the critical factor.

In a session, the hypnosis gains access to the unconscious mind and floods it with positive suggestions to overcome negative habits like smoking, overeating, etc.

If a person has an emotional problem like depression, the hypnotist can tap into the storehouse of memories in the unconscious. The hypnotist can guide the client to the initial causes of the depression and help the client overcome the effects of the trauma. This can be a complicated process and not all hypnotists have the training to do this.

There are crappy hypnotists out there and good ones. Try to find a hypnotist with a good reputation. A personal recommendation from someone who has seen the hypnotist can help a lot. I don’t think most hypnosis CDs are of much value. Generally, you need personal contact with a good professional. I wish you well.

You leave it down by the side of your gum for up to 3 to 4 hours, chewing now and again then replacing down by the side of your gum.

It worked for me, but it will take years of taking them.
