I was a smoker for 18 years, I just turned 35 and I quit smoking cold turkey 9 days ago, and I feel great!!!! All my craving are almost gone, I have a my only craving at night after my 4 kids go to bed, but even that one is getting less and less. I feel 15 years younger, I always felt that I had some sort of desease, I always felt sick and now that all went away. So, my question is...Do you think that along with all the bad things that ciggeretts do to your body, do you think that smoking can cause bad depression? I have a had depression forever and I blaimed it on a hole lot of things and never could pin point where it was coming from, now, I feel so happy and depressed free.
