My dr has had me on Chantix since last July!! The first 3-4 months oh yea I was very bitchy.. good Lord was I ever! My husband who I had warned of the possible mood swings got upset by it as well as my kids and some friends. I just felt like I wanted to rip everyone a new one and I couldnt control it and it drove me bonkers. It's better now though thank goodness
Now you might be wondering why the heck I'm still on it? Well, I found that if I wasn't taking it I wanted to smoke and would, alot!! I never totally quit with it either... I went from a pack and a half a day down to 3 or 4, sometimes less. I only take 1mg day now and have since November. I'm still smoking the 3-4 a day... not grumpy anymore though. It's expensive staying on this med for this long but like my dr said, I'm spending less then I would be if I were smoking 1.5 packs a day. Also many people who go on the patch or gum stay on it long term sooooo she told me to keep taking it and keep trying to give up the few I'm still smoking out of physical habit and not addiction... sorry I rambled
Keep apologizing and make sure the people around you know this is a side effect that will go away and to please bear with you. And try to cut your smoking down quickly so you can get off it! I really want to not have to continue taking this pill forever.
Good luck
