I am glad I found your post to explain why I feel so cruddy. I am exhausted today and have felt many symptoms you describe. I honestly did think after two week + I would be back to "normal". Disappointing but good to be aware of that.
A lot depends on the length of time you drank and the quantity. I drank a magnum daily for ten years and felt awful for three months. It's a long slow process that AA helped me get through. The support of other people who drank as I did was invaluable.
