Thanks for posting Lucrezia, I like your honesty. I've quit more times than I can count, and Ive always ended up returning to my old destructive friend, alcohol. And it's because of what you talked about - I still get great pleasure from drinking. That's the struggle - alcohol treats alcoholism.
The problem is the consequences that come with our drinking. The hangovers, wrecked relationships and careers, wasted time and money, etc.
The hope is that we can learn to live and enjoy our lives without alcohol - something that seems almost impossible in early sobriety. But listening to others that have achieved that proves not only that it's possible, but likely if we quit drinking and work on recovery.
If you really believe you're an alcoholic, I think the decision to quit is the right one. It's only going to get worse.
