Hey Bubba, I've been thinking. The way this intro reads, especially when you say things like "just one" it sounds like (for you) the experience of quitting nicotine has given you a ton of anxiety and depression. However, I think there is a different angle here, one that most of us are familiar with, and that is the self-medicating component of nicotine addiction. Nicotine is an anxiolytic - like Lorazepam. Most of us have self-medicated with nicotine for years. But when you remove your maintenance drug for anxiety, you're still left with the anxiety and/or depression. You're 70+ days in and there is no nicotine in your system, so you're left with the anxiety and depression - and probably the first time you've ever had to face that head on without nicotine as a crutch. Anyhow, I think this explains why you feel this way so long after having killed the can.
Oh, and that comment about taking out the "addiction" in you. This is 100% true.
I am an addict. I'll always be an addict. Today I sit at 1622 days quit and I am no longer an addicted addict. In other words, I am an addict, but I am not addicted. And this is why I post roll every day like my life depends on it ...because it does.
