Where Next?

After realizing that I had to "stop" with the alcohol, I did. No withdrawals, no dt's.no temptation to drink period....but the shame, depression, loss of appetite, has been more than terrible......The anger towards myself, and the addiction is overwhelming at night.......Being a single man always, I guess I was sorta "courting" the alcohol.......It gave me pleasure and didn't argue. Humans were too complicated, and always seemed to "want" something from me, be it physical, or to babysit their needs.....
I had no clue that I was using alcohol to self medicate myself to sleep 7 nites a week....My job was great, and a perfect  trigger, because the workday normally ended by 2-3pm, with plenty of time to start in earlier...Blah, Blah....I guess hopefully there are some of you reading this, that may be able to recommend how to "replace" the time that was once wasted....How do you feel better about what's gone, and are there any good vitamins or diets, that can improve your mood? I am trying, and any little suggestions will help me move forward.....Thank- you! James
