So I have been on and off this bandwagon for sometime now. I quit years ago before I left for basic training, and then picked it right back up when I got to my regular duty station in Kentucky. Quit again 5 years after that with the patch and that didn't seem to last long. Quit again, or as I like to call it "currently refrained from smoking" using the blue e-cig and didn't cheat for a year. Just started Chantix not totally sure about it, anyone else here use it? I am only on my 3rd day and yet I notice I am getting more aggressive, and seem a little short tempered, and shit I haven't even stopped smoking yet!! Is this just my body getting used to this or what? Can anyone enlighten me on their experience?
