try this homeopathic spray from the brand King Bio
it had a 5 star review on Vitamin Shoppe's website (albeit just one rating)
I haven't used it but I used the brand's smoke control spray and after 10 years of smoking I was able to quit happily almost 2 years ago.. and that's all I used, no nicotine replacements or anything like that.. I've used other forms of homeopathy as well so I've seen it work.
also you could try eft
