I have a dear friend who's been sober almost 20 years. He got a DUI and that was it, he quit. We were talking the other night and when he first quit he went to a few meetings, but he said it wasn't that difficult because he had made up his mind that he was done and that was that.
About a year into his sobriety he thought he'd try having a glass of wine. He ended up having six, and that's when he realized, "I can't drink just one drink. Ever." He accepted that fact, hasn't touched it since then and has a wonderful life. He's such an amazing, fun person. We have more fun and laughs together now than we ever did when drinking heavily. At least we remember them!
