I smoked at least a pack a day, sometimes 2 packs, for 35 years.
Overall caveat - you have to really want to quit, not just go through the motions so you can say you tried. Must think in terms of, that you Will absolutely quit, no matter what.
1. I found this web page: http://whyquit.com/whyquit/A_Benefits_Time_Table.html
- something to think about
2. At the bottom of that page are links, 2 are to download PDF booklets - read them, more to think about/get into your subconscious
3. Bought a hypnosis CD - the effective ones are all similar, getting you relaxed, making the suggestions, etc. You don't actually "go under" - you are aware of what is being said.
I read many reviews of such CD's and chose a 3-CD set by the "Beverly Hills" guy - listen to #1 for a week or so, then #2 to actually quit, then #3 for a week or so after quitting.
I listened to them right before sleep, when I was awake enough to stay awake for at least one run-through, but I had it on an endless loop so it played all night long while I slept.
Days 2-4 were the worst for cravings, but not too bad. During those days I did things to give myself an "investment" in staying quit, like laundering all my clothes, blankets, washed walls, cleaned car interiors, etc.
I've been smoke-free over 4 months now, has not been a problem.
PS - I have the CD's for sale on our local craigslist, would sell them for $20 shipped if you are interested. Or just search Amazon and read reviews for different ones.
