I have often wondered the same. But that's because I was too blind to see the truth. Sure, when I am sober I still have mood swings-- from elation to anger-- but I can actually feel them. When I am drunk I have the same swings, but I don't remember them at all. When I am sober I am quick to apologize for wrong doings, when drunk I don't care, until the next day when I am sobering up, in a panic stricken state of omg, what did I do or say. For me, sobriety doesn't allow me to hide. It allows me to be me, who I really am. And drinking robs that from me. I am learning to be comfortable and confident with myself. When I am drinking I don't feel secure in who I am, and I feel like a spectator because I typically have to ask others what happened. Easy does it, don't over complicate it and allow yourself to feel these things. There is a lesson in every single action and thought.
