Carol excellent link, I will have to mention that to some folks I know who like me stratch thier heads every once in a while when they want a drink. It is like we are doing so well, could care less about a drink and BAM!!!! All of a sudden we get really different and in many cases we fool our selves into thinking a drink is not a bad idea.
Mongo interesting stuff, there are a couple of folks I know who still have the shakes even though they have been sober for several years, thier mind is crystal clear though.
