Hi, I've suffered through alot of winters with being emetophobic, though the last 2 years i haven't had the stomach flu, but for some reason today my anxiety has been acting up really bad and this has been giving me a bad day so far, so in preparation for this winter i need to know some ways to avoid the stomach flu, i heard the grape juice thing works but i want a daily thing that prevents it, and drinking 3 cups a day is expensive and not healthy, is there any other alternative? If i have a reliable and easy way to prevent it, my anxiety goes down and i actually get a huge feeling of confidence, So if anyone has any good advice please help, i really want to get this thing out of my mind this winter so i can focus on other things.
