Hi All. I'm 37 smoked since age 16 pack a day. Today is day 74 clean. It's been the toughest thing I ever did and still constantly think about smoking. The thinking lately is more aggressive to the point that I am afraid of myself that I will just buy and smoke again. I have a constant feeling of loss and not happy at all. Mainly using gum as 2 prior quit attempts on Champix failed! I really wish to relieve myself of this horrid feeling!
