Rehab is great, they clean you up to start your road to recovery. Unfortunely I never stayed sober after multiple rehab stints because when i left I wasn't truly working any program. I think deep down inside I still wanted to drink I just didn't want the consequences... but 2 firings, 2 duis, lost relationships, poor mental and physical health I can say in my dr Phil voice.." how's that working for u " to myself. Just relax and get yourself pumped up that your on your way to getting help. Don't worry about all the little nuances.
