Paintbox, what people tend to forget is that the old weed tastes and makes you feel sooooooo good !
Or that's how your mind seems to work.
Actually, the nicotine doesn't make you feel good, the withdrawal makes you feel lousy, the fag just helps you feel normal again. That's why that first one in the morning tastes so good.
Try and steer clear of the doom and gloom folk. You are addicted to a chemical as powerful (and ? as dangerous) as heroin, and you need help with your addiction, not telling off.
It looks like you have reached the most important stage, you actually want to give up. There are some good hints and tips contained within this thread, and if you perform a search within pprune, you will find lots of solid advice.
There are many interventions which may be of use to you. Nicotine replacement therapy (gum/inhalator/patches/lozengers) and zyban (a drug which helps with cravings) can help. Accupuncture, hypnosis, herbal therapy are not likely to help.
I'd be a little careful with zyban (chemical name buprpion) if you are currently flying. It can induce fits in some succeptible people, and I expect that it is contra-indicated for pilots.
Have a chat with your local community pharmacist/GP/practice nurse. Smoking cessation is meant to be a government priority, and there is lots of help out there. Good luck.
