erm, there are other ways to smoke that stuff. i would put it up, but im not sure if its appropriate. you must addicted to tobacco if you cant give up. as for actually giving up, its a bitch. try nicotine patches. but not the nicotine gum, apparently it makes you sick. or just try and cut down gradually at first. if youre doing exams, then now is probably not a good time tbh. wait untill theyve finished, you will much less stressed, so it will be a bit easier.
