Blood sugar level is a factor in the addiction. When the cravings are successful gone, throw away the candies. Take extra calcium and eat chamomile 3-6 times a day. Both will help relax during the withdrawal period. Vitamin B complex is also important for the nerves.
Lobelia contains lobeline, which is similar to nicotine.
It is non-addictive, but helps a person quit tobacco. The result will be nausea, which the person will associate with the cigarettes. This kills the desire for the cigarettes. If the lobelia method is not used, the alternative must be a definite quit all at once approach. See the author's book.
