How wonderful to hear of your positive experience in hospital. And well done to you for owning up to your problem and facing it. Recovery is a beautiful place - I recommend the support of other alcoholics to get there, whether you subscribe to their system of recovery or not, Fellowships are awesome for support in difficult times.
Commit to your recovery and work on changiong your thought patterns that lead to relapse and unhappiness and you'll be on the right track.
