I am no expert, and I was the one that stopped drinking in our relationship. I think I know how he is feeling. Those first few weeks I was sounding a lot like him. I think just know that it will get a little better with time. Its a very scary, rocky road those first few days/weeks without alcohol. Try and be patient. Take care of yourself too.
I am sorry, I don't know what else to say. I am sure you will get some other advise here.
My husband is bi-polar and he struggles everyday with his mind, how he feels, making decisions, etc. Its even more of a struggle once you add alcohol and drugs into that system.
Hang in there.
