I'm addicted to smoking so much. If I let myself without a cigarette for an hour, I feel huge headache ??

I don't know of anything that can stop the withdrawal symptoms. But I can tell you that when I was quitting, it helped to go for a walk. I knew when I would begin to need a cigarette, and about five minutes before, I would go for a walk. Then when I got back, I would find something to keep my hands busy, like sewing or baking anything to keep me too busy to smoke. That would get me through a while, and then I'd have a cigarette maybe an hour late. But I only smoked about one every two hours.

Quitting cold is difficult, because it hurts, but the bad withdrawal only lasts three or four days, and if you can find a place to be away from people whenever you feel a bad reaction coming on, that is good too. And once it's over, you need to find other ways to get past the habit. Do you smoke while on the phone? Instead get paper and pencil and doodle while talking. Smoke when having a coffee? Instead, take your coffee to a different room and read or knit or sew, or whatever can keep your hands busy.

Lastly, I found that taking a few minutes to do some deep cleansing breaths, whenever you feel the desire for a cigarette, really helped.

Good luck. I've been smoke free for twenty two years, and have no desire to go back.
