Discovered this site a couple of days ago and have been considering giving up for years. A lot more seriously this year and finally took the big step today. Now managed to get to the evening, too jittery all day to concentrate on doing anything constructive and sitting on my hands in front of the tv for the rest of the evening. Will have to go to bed early today.
Always said that if I ever did it, it was all or nothing and cold turkey would be the only way to go, which is what I've done.
