Hooray for you Helen!! You are taking your life back!
Your quit is directly linked to your attitude...it can be as easy or as hard as you want it to be. An educated quit is by far the best...as you learn about nicotine addiction and how smoking has changed the chemical makeup of your brain, it's easier to understand cravings and how to avoid the pitfalls of quitting: Hungry:Make sure you keep you blood sugar up, Angry:keep track of you emotions, Lonely: talk to us if you need, Tired: sleep it off.
Read everything you can, here and whyquit.com are great resources.
Congrats on the best decision you will ever make...when you make it to the other side; you won't even recognize the person you are now. It's a life changing adventure.
