I passed the three week mark yesterday. For the first week I was as sick with the flu as I've ever been in my life. Didn't even want a smoke. Around Day 5, when I was feeling a little better, I caught that first craving. I decided I'd made it five days, even if it was due to the flu, so I would see how long I could go. I'm trying to use my natural stubbornness to help me out. Every day I add to the total makes me want to relapse that much less. I'm not using anything besides willpower, although I would certainly advocate using whatever works for you. The funny part was right around the end of Week 2. I think the withdrawals were just especially strong at that point. Nobody around me was safe. For about three days my inner dialouge was like a more vile version of Grumpy Old Men. Traffic, waiting in line at stores etc etc. Since that passed, though, I've been fine.
I was a smoker for 11 years. I tried to quit several times.
The difference this time is I actually WANT to quit. It's been said many times in this thread, but it's the truth. If you aren't ready to do it, if you don't want it, it won't matter what method you use. Incidentally, it was stumbling across this thread that first got me started thinking about quitting again. So cheers to y'all...
