When he wakes in the morning he knows that’s about as good as he will feel all day.
I guit for a year and a half because I drank so much that it made me feel worse than not drinking. I quit completely because I bought into the myth that an alcoholic cannot cut back, he must cold turkey. I found (for myself) that was BS. Always remembering how bad I felt just before I quit I set a limit that I hit every evening and have not exceeded in over 2 years. I look forward to it each day and it eases the pain for a couple hours. I don’t expect any more from it.
Only you can answer your question.
