It sounds like some of the ways you are feeling are similar to the way I felt up to about 3 months, and then gradually lessening. I am just under 5 months. The surprising calmness which I came to realize was a numbed out lack of interest or enjoyment of anything was like a fog. It seemed that without alcohol that I did not have the capacity for laughter or finding anything humorous, even though I had been able to laugh easily with or without a drink in hand. Turns out it was not the lack of alcohol producing that effect but the prolonged withdrawal. Sure hope you will find your zest and interests returning soon.
