Sometimes I think we have a tendency to look for that "magic bullet." Pretty sure it doesn't exist. From my perspective the most effective means of eliminating an unwanted behavior is cold turkey. Any behavior modification professional is going to tell you if you take something away(nicotine), you need to replace it with something. The short list in this case would be herbal alternatives, any # of NRT options(which I don't condone) or other means of oral stimulation ie gum, seeds, toothpicks, hard candy......
Prescriptions such as Wellbutrin or Chantix may have worked for some and that's great. But check the research, longterm they aren't nearly as effective as going cold turkey. BUY INTO WHAT THIS SITE TEACHES AND CAN OFFER IN REGARDS TO SUPPORT. YOU WILL FIND NO STRONGER OF A BROTHERHOOD WHO WANT TO HELP YOU THROUGH THIS. Ultimately you're going to have to decide how important your nicotine addiction is to you. If you want to quit and stay quit bad enough, then it's "go time." Make that commitment each day to stay quit and focus only on that given day. I'm only on day 10. Can't tell you what tomorrow will bring but guess what, today I will be nicotine free there's no denying that.
