I smoked since mid teens, quit twice with willpower, lasted a year both times. Two years with Allan Carr book. Last time I quit I went for champix I only managed to take them for around 3 weeks as they made me so ill. Have not smoked since and don’t miss it, not tempted at all, it’s been 4 years now. Would recommend the champix even though I did suffer on them and two months after!!!!! Worth it 100%
