Congrats on one month!! That's awesome!
As others have said, there is nothing wrong with feeling great! Just be sure to keep your sobriety a top priority. I made it to 39 days a slipped for two and had to start over. I got overly confident in my ability to not drink and it got me. Now I have learned to enjoy my sobriety and the freedom that comes with it while also keep a vigilant eye on that nasty AV.
