Patrick...
If you've only been clean 3 days... those cravings are your body talking to ya..
Their getting desperate.. ;o)
I have learned to come at cravings from the side. I acknowledge them.. that I'm powerless to make them go away... and then I mentally connect to my HP and try and stay there as much as I can.
Doing something that needs to be done is usually a good way to decoy myself from obsessing as well.
Stay close here today in any case ... we'll keep you company.. ;o)
