It is very hard to quit. I started smoking at 20, not to join a crowd, because only 1 out of the crowd smoked. You know, just sitting around bored, puffing away at one or two. Well, it's now 5 years later, and I'm still puffing away. It's a pack a day habit now. Tried to quit a few times. The most successful time was last year, at around thanksgiving. Was able to stop for 2 weeks, only had like 1 or 2 a day to calm the nerves.
You know how the nicotine affects you mentally? It's very addictive.
It's useless to tell us smokers how bad it is and this and that, we know that already. Just can't kick it.
