Patience is the name of the game. The brain is a dynamic organ and changes throughout life, and can repair itself to a certain extent given time and healthy behavior. Stay away from the alcohol and the fuzziness starts to resolve itself. I'm at 23 months off alcohol and every day my perspective changes and improves to some degree. I remember when I was drinking, my worldview never shifted. The world owed me everything, and I owed it nothing. Now I'm beginning to understand that the reverse is the truth, or at least a way to live a more fulfilling life.
