Even just being here is helpful to me when I feel that craziness. Kudos to you for posting!
Busy yourself with something else, particularily something to do with recovery. Read the forums, literature, call a friend. It does pass but it feels horrible while it is happening, I seriously feel possessed sometimes but if I hang in there, and do something else, the feeling passes and then I am SO glad I didn't drink.
Good luck, glad you are here!
