I was on Chantix for an entire year... yes, 12 long months of hell because my dr is an idiot and must have been getting some kind of cut on the price I paid for it... $130 a month plus I was still smoking 8-o Not kidding!! That stuff not only made me feel extremely moody but it made my ears ring very loudly, weight gain, bowel problems, headaches, tingling and numbness
throughout my body, high blood sugar... they now say Chantix can cause diabetes and other heart and health problems. Coming off of it was 3 weeks of hell also as it IS addicting or rather 'habit forming'. The worst part is the mood changes... not just .....y but depressed, sometimes overly happy, hyper, just plain weird. I hated that crap... so glad to be off it.
