Look, I think you're doing really well and seriously well done on tackling a potential relapse by sharing here. I wish I'd done that before I headed into another relapse a few weeks. If I'd taken 30 minutes to post here or talk to someone on the phone I could have avoided a whole lot of trouble.
As for sushi, I adore it and I used to live in Tokyo! Can I just make the observation that the Japanese never, ever drink it with wine? It doesn't complement the taste of raw fish at all - it's far too acidic and tastes vile with soy sauce. In sushi bars in Tokyo, it's common to drink it with hot green tea! That's a bit of an acquired taste I know, but it does complement the fish really nicely. My personal preference is to have sushi with a light, chilled brown tea called gen-man-cha. That way you really get to enjoy the texture of the fish, especially lovely things like salmon fish eggs, known as ikura. Have you tried them?
Oishi! (Delicious) as the Japanese say!
