There are standard ear acupuncture treatments for helping to stop smoking, weight loss, and addiction. The worst part of breaking any of these habits is the withdrawal, and that is a big part of how acupuncture helps, because in addition to helping with the physical symptoms, the treatments help to calm the mind. The usual treatment is 5 standard ear points , treated with acupuncture on one ear, and earseeds placed on the same points on the other ear. The recommended treatment course is to have 3 treatments a week, for the 1st 2 weeks, then 2 treatments a week for 2 weeks, then once a week. Usually, 4 other body points are also used during the treatment to help strengthen the treatment. I have worked with many clients using these treatment protocols, and , guess what,  THEY  WORK! I have worked out a "package deal price" for these protocols, I want them to be affordable to anyone who needs them. Please ask me for details!
Need some help with any of these conditions?  I'm here.
The other interesting fact about ear acupuncture is that it can be used (I usually include it in a treatment) to help reinforce the energy of a treatment. For example, If I treat someone for a lung problem, I place an earseed on the point on the ear that relates to the lung, and instruct the client to work with (squeeze the ear area) to re-energise the point. Earseeds are absolutely painless, and when used, will actually help to keep the energetic going in between treatments.
