Cold Laser Therapy

I haven't quit as yet but I know the time has come after smoking for 40 + years.  I am looking at all the options for help.  Previously I have had some success with Nicabate lozenges but find they are currently off the market.

I am wondering if anyone has tried cold laser therapy to quit and, if so, was it successful?  I am considering trying although it is very expensive at around $700.  I am certainly prepared to spend this if I think the method is a successful one.  

I would really appreciate any feedback from those who have tried it.
