My experience of what you describe is the mental obsession to drink. After the first few days of withdrawl, there is no such thing as a craving. Craving is a physical thing. It is activated by putting alcohol in my body. What I have at however many days after I quit and I'm thinking about drinking, desiring drinking is MENTAL OBSESSION. What worked for me is getting into AA and finding another alcoholic who showed me how he got sober and has stayed sober.
