Try anything that will work for you. Everyone is different. I quit using the Ex plan. That behavioral approach was AMAZING for me. Really worked. For my first week off cigarettes, I used nicotine gum, but only about two pieces per day for the physical craves and withdrawal symptoms. My first week symptoms were fuzzy thinking, agitation, headaches and restlessness. These symptoms make it impossible for me to do my job in a safe way, so NRT gum got me through it just fine. I stopped chewing it in the second week (by that time my nicotine blood level was minuscule). So, I had a very pleasant quit- "all-in-all". I have quit many different times before. Even each QUIT is different for the same person. I would suggest you prepare well, have a back up plan, change plans if you need to, and do whatever it takes to quit!
