I don't understand these horror stories. I am bi-polar, am taking Lamictil, Seroquel XR and Lithium. I have been level for 3 years, some minor irritability occasionally. I used Chantix to quit smoking for the entire 3 month term and did not experience any of the side effects reported all over the internet. I did experience some mild irritability and racing thoughts but is nothing out of the ordinary for me whether I was on Chantix or not. My opinion, is if one is level enough to recognize his/her own mood swings, then one may be stable enough to use Chantix and manage the adverse mental reaction. Maybe it's a matter of willpower, I don't know, I only know that I had no severe problems and am now a successfully reformed smoker.
My educated opinion, is that the mind is a very powerful thing. Alot of people start taking meds expecting some side effects listed. Once one convinces him/herself they will experience at least some of the side effects, then most likely you will as your mind will subconsciously manifest these. It's directly related to a placebo effect. This goes back to my original statement about willpower. If you are mentally prepared before taking it, and not telling yourself "oh i'm bipolar i'm going to get depressed or hallucinate, or not get an erection (which is not an OFFICIALLY listed side effect btw)".
I also spoke with my psychologist regarding using Chantix before starting it, and being bipolar on meds. She was totally fine with that, only listing the side effects I should watch out for, and the irony about the side effects she gave me? They were the same exact identical side effects of Chantix as if I were not bipolar and on meds. I've noticed a lot of people with bipolar disorder claiming to have these symptoms, try searching for claims of these symptoms in people without bipolar disorder, you will find there is about the same percentage of "normal" people having these problems as people with bipolar disorder. Let's not adopt that "i'm special" attitude and focus on just the relation between Chantix and bipolar disorder.
champixsucker, are you sure you don't have a deeper mental issue that Chantix may have simply brought to the foreground? You are the only post I have seen throughout the internet that claims long term or permanent symptoms from using Chantix. For example, I lived the first part my life up until I was 25, without any kind of mental issue or bipolar disorder. I then joined the Navy and the stress and structured lifestyle brought my bipolar disorder out. Traumatic experiences can and will do this to people who had dormant issues or genes and will activate. I just can't see blaming all of those issues on Chantix, maybe if you experienced those symptoms and they went away when you stop using Chantix then I would be inclined to believe it was just the Chantix. For example, when the psychologist originally began my treatment for bipolar disorder, she gave me Abilify, I began having seizures, when she took me off the Abilify, I ceased having seizures. There is a med I do know can cause permanent issues, that is Lamictil, it can cause "ticks" if you will, involuntary muscle spams, and that can be permanent. Yet these are well documented, I see no documentation on permanent side effects to Chantix.
I am not defending Chantix in any way, I am only sharing my experience, and my own educated opinion.
