The mood swings and tides of craving happened to me too, along with the insomnia, shakes, headaches, fever and chills and bowel troubles of alcohol withdrawal. There are acute withdrawals and longer lasting symptoms as well.

I credit Antabuse, individual counseling and AA for my initial recovery, and AA and Talking Sober for my continued sobriety. Here is an excellent list for you from another TS member.
