So I just left a basketball game and 2-3 of the girls on the other team was throwing up in garbage cans during the game with the stomach flu. After the game was over I washed my hands, came directly home washed them 2 more times and then ate. My friend that i talked to in school yesterday had it and just got sick last night. What if I have it in my system? Does the grape juice really work?!?! I looked for it at a gas station but all they had was Grape cranberry juice. Is it ok to use that? Someone please help!!
