All have their own websites. Read about them, stop drinking, and follow one of those methods. AA isn't for everyone and isn't the only way to stay stopped.
Getting fired for drinking on the job, calling in sick too often or coming to work while still hungover/drunk could also cost you your job.
Make a decision to stop and stay stopped! You CAN do this!
