I never had a DUI or hit rock bottom either but my behavior was getting more erratic and I had gained weight too. I feel so much better without it and I don't miss it at all. At first you think life will be boring without drinking but I found so many new interests I don't miss drinking at all. Really drinking was boring for me. I wasted way to many days sitting in front of the tv on the couch. Also drinking heavily is bad for women. Increases risk of breast cancer etc. I think that scared me too.
Alcoholism is progressive. I don't know if you are one or not.
