fuckin cigarettes..i smoke about half a pack a day...i definitely feel a little tense when i haven't got one. if i run out and cant get a pack that day i've gotta find one or i won't be too pleasant. I wanna quit and hopefully i can do it over the summer. I'll be very busy then and hopefully i can keep it out of my mind since i have work all the time. that is the hope anyway. in answer to your question though..i seriously doubt any of your withdrawal is nicotine related. If you don't smoke 10 cigs a week then it isn't gonna have that much of an effect on you.
