I am sorry to hear how much you have been struggling with quitting. Some members here say it was the hardest thing they have ever done - but the rewards are certainly worth it.
It sounds like you have a lot of quit experience. That is great that you have tried quite a few times. What have you learned from those quit attempts? What works for you and what doesn't?
Welcome to the SSC. It's okay to fail, just don't quit trying otherwise you have failed. It takes most people a number of attempts before they can actually quit. How long have been wanting to quit? How many times have you tried to quit? How long was your longest quit? Do you know why you started smoking again? What's your motivation for quitting?
I'd suggest that you continue with the program at the top of the page. You have step one done already. There will be help and tips in each step that will help prepare you for your quit. Read through the forums and try to learn all you can about what to expect so you can prepare for it when you start your quit again. You might want to consider NRT too. Nicotine Replacement Therapy helped me in my quit. I'm not sure if I could have quit without it. It took care of the physical part and let me worry about the mental part which, in my opinion, is the hardest part.
It does take a lot of willpower as you've said, and I'm glad that you have admitted to yourself that you are addicted. Nicotine is a terrible drug that is VERY addicting. That's a step in the right direction!
I've been wanting to quit smoking. I know all the disadvantages and tragedies of smoking. Yet am unable. Though I know that the will power is within me I have failed again and again and again. I know if I really wanted to I can. But it's just not happening. I feel terrible and yet am addicted. Any suggestions.
