It takes a while for your brain chemicals to level out. A doctor told me that alcohol provided a temporary supply of the "happy chemical" and now that the substitute is not there, my body has to take the time to learn to make it on its own. It takes time and patience to let my body do what it has to do to make up for the false happiness I've been supplying all these years.
In my experience (1 month sober, 6 months reducing) the moods begin to level off. I still get sad but not nearly AS sad. I still get mad but not nearly AS mad. And the sad and mad feelings dissipate much more quickly.
keep trudging along!
