Absolutely this is for smokers too. I still smoke as well and have tried quitting several times and ITS SO HARD.

One of my best friends quit smoking about 8 months ago and then she was getting way depressed and feeling crazy. She had a visit with her doctor and it came out that she'd been feeling depressed. The doctor asked her if she'd quit smoking recently. I've always known since high school that nicotine mimics a chemical in our bodies, and so when we smoke, our bodies quit making that chemical and thats why its so hard to quit.

Turns out, that chemical is the one that helps us feel happy. So when we quit smoking, we're literally not making enough happy chemical. So my friend's doc put her on Prozac on a temporary basis to help her jump start her body into making that chemical again.

Somehow, knowing that, helps me understand why its so hard to quit and helps me not be so hard on myself. Next time I'm ready to quit, I might talk to my doc about that. I guess thats why Welbutrin and that new Chantix helps people quit, because it jump starts the chemical making process that our bodies "forget" because of the nicotine.
