“I caught the flu last season — fever, body aches, the works. Started Antiflu within 24 hours. By day 2, my fever was down. By day 3, I felt human again. The metallic taste is real, but it’s manageable. I’ve also used it for post-exposure prophylaxis when my kid brought the flu home — didn’t get sick.”
