New to this site, been on the champix for 9 days and counting. This is my first day stop smoking. Is it normal to get mood swings and be aggressive?? This has happend over the last 3 days and i have also walked out my job. Sometimes i feel very relaxed and other times i loose the plot. Being feel sick alot on the champix but would rather feel sick than smoke. Anyone elses experiences i would appreciate that has had side effects???
