Quitting cigs was hard for me since I started young, but I managed to cut back and eventually stop. It's difficult though, because every time you see or smell a cigarette, or experience a stressor, the need comes back. It's hard, but doable. Sometimes finding other ways to release stress is helpful. For me it was singing, and that helped because I couldn't sing if I smoked too much (messed up my mouth and throat) and I like it much more than I liked cigarettes, so it motivates me to stay away from them.

I wish you the best. You have the most important tool, which is the desire to change. With that you can accomplish anything!
