Nicotine is one of the hardest addictions to get over. Nicotine is as addictive as heroin or cocaine. I wish you good luck, but don't blame yourself if you can't quit.

I quit in 2000 and I think the only way I was able to quit was because I worked in a place where everyone smoked, so I got a ton of second-hand smoke. I doubt I would have been able to do it otherwise and it was still one of the harder things I'd have to do.
