I am 20 years old. I was a smoker for 4 years. On 27 April 2013 I decided to quit. No pills, no methods, only me and my will. I was alone in a foreign country, so it was hard, but I guess it was worth it. One year later, without having smoked a single fag, I feel a healthier person. I can't tell you how happy and proud of myself I feel.
There are only two small issues. First, I have gained 20 kilograms, which I still can't get rid of and continue to eat a lot, and second, I feel I have some studying and remembering issues since I stopped smoking, which probably is only in my head and is not related to this. I really have to deal with both of these issues, but I guess I can make it.
I just wanted to share this with you guys. I want to thank all the people who supported me on this forum through my journey and the numerous failed attempts before I could make it. I also want to thank my girlfriend, who always stood next to me and also stopped smoking the same way I did. I really appreciate your help and hope that other smokers will also find the will and the support here to get rid of this terrible habit. Good luck!
