Not me personally, but I've known many who have received food poisoning from not-so-fresh sushi. One friend got burned 3 times from 3 different places in Los Angeles. After that, he began taking charcoal before eating raw fish, and it never happened again. Taking AC is like carpet bombing your stomach - nothing survives, including beneficial flora/fauna that your gut needs 4 balance. I only take it as needed, or if your dog swallows chocolate or cannabis, give it to them.
