Firstly, welcome to the forum.. I'm a long term member but have been a bit absent lately and miss many new people.
I've never been a smoker, so I can't give you personal advice/experiences. BUT it's a great thing to do for your health and even the health of those around you (through second hand smoke). I know that changing behaviour happens in a few stages (I study psychology and this is a model of behavior change).
Precontemplation is where you don't think the behaviour is a problem and don't think you should try to change.
Contemplation is when you think maybe you should change it, but aren't really planning to
Planning, where you get information about ways to change the behaviour and make a plan
Implementation of the plans
Maintenance of the change.
Sounds to me like you're at or around the Planning/Implementation stages and one of the most important things is to put as much effort as you can in to the planning. Same goes for weight loss too BTW. Also, implementation doesn't always work and you might relapse (either from implementation or maintenance). You might be lucky and get it right first go though! What is important is that if you relapse, you don't go all the way back to precontemplation and think things like "well obviously I can't do it, I won't bother". Much better to go back to the planning stage and reassess the plans to see what went wrong and make new plans to deal with it. Every relapse teaches you something new and takes you closer to sucess (in a round about way).
All the best with it!

Back to the drawing board - Let's do this thing!
