Last week I did. And what are you waiting for? I don’t think there is a need to explain the benefits of quiting. And, IMHO, all you need to succeed is a real desire. It is possible. Many people already quit and many more will do in the future.
If you do want to quit smoking and just need some more information I strongly encourage you to contact your GP. I’m sure he/she will be more than glad to help.
If you think I can help just comment on this post, contact me directly or use forums and I’ll do my best.
