Try reading Alan Carr's the easy way to quit smoking. It really helped me. It talks about the fact that we smokers have totally been duped into thinking we have to have nicotine. It is actually out of your system in a couple of hours, not days weeks, etc. Of course, the triggers to smoke are always around and if you can learn to notice those, you can get a grip and talk yourself out of it.
You are only angry because when you think of smoking you are that TEENAGER that wants to rebel and smoke, rather still stuck at an arrested form of development. You are NOT that dumb teenager any longer, you are a responsible adult who should do what is best for herself and her family. Right? You can do this. PM me anytime you want a cig and I bet I can talk you out of it. Problem is the cravings don't really last that long..so REALIZE that!!! Try quitnet.com tons of support there too! Won't say good luck as there is no luck involved.
