I couldn't figure it out either, so I just went for it one night. I didn't have any "treatment affects" afterward. I ate
cup of miso soup
2 pieces of eel (nigiri)
1 unagi hand roll
2 pieces of tuna (nigiri)
1 piece of yellow tail (nigiri)
4-5 pieces of other rolls (tuna, eel)
1 piece of flying rowe (nigiri)
it was alot of sushi and it tasted great with no effects!
