In case it helps anyone struggling: Anecdatally, I stopped drinking alcohol more than a year ago because I was feeling worse and worse for a day or so after one can (I tended not to have more than that). I was also having trouble sleeping, wasn’t remembering dreams, and was more irritable than I liked. I think I have enough alcohol dehydrogenase, given my ancestry. Anyway, I feel better on all counts, saved money, and no longer have the craving for a drink, unlike with chocolate (easy to manage if my spouse hides it) and coffee. I don’t need these luxuries and I feel better, more empowered, when I can choose to consume or not consume each day without compulsion.
