Well I made it this far! Despite a few ridiculous temper tantrums over the last few days I have made it to day 5!
Minor grumpiness at work on Friday (day 2), but managed to keep a lid on it and maintain a sense of (vague) professionalism. I fared slightly worse over the weekend with my girlfriend, but she is being very supportive and managed to put up with most of my grumpiness. Sunday felt much better, like the worst of the nicotine-related rage had subsided and since then I feel like I might be over the worst of it.
I do have concerns though that I do actually still *want* a cigarette... maybe that feeling won't ever leave me. I was thinking of reading Allen Carr's book to try and get me out of the mindset that I am denying myself something that I actually want. It's been quite comforting reading all your stories of your struggles on this forum, I wish you all the best of luck for the rest of the week, and forever.
