Those early day cravings are really difficult. Please know this - it isn't always like that. Those cravings do fade away over time until one day you won't remember the last time you had one.
The important thing now is to do whatever it takes to get through those cravings. Outside support can be very powerful and effective. One item in your sobriety toolkit can be a promise that if you feel in danger of caving and drinking that you won't go ahead until you've picked up the phone and talked to someone or come to SR to post for support. Sometimes even a simple non-sobriety chat with someone can refocus you when you most need it.
