Welcome aboard, @Vivianne
You are doing a great thing by quitting smoking. Try to focus on the positives which you will eventually find out far outweigh the early, short-term negatives. There really is nothing at all positive about smoking but a lot of positives to putting smoking behind you for good.
Joel Spitzer's videos are definitely worth your time but if you can access Allen Carr's book, "The Easy Way to Quit Smoking", I would also recommend that. It really helped me see smoking in a different way and was a good resource in my quit.
Stick close to this site. There is a lot of knowledge, fun, and distractions to help you.
It is great to have you here.
