Another thing is, you can drink grape juice (no sugar added), daily also, cuz the acid in the juice will prevent any
virus from settling in your intestines. All I do is, every evening, I pour my Kids (ages 7&3) a 1/4 cup grape juice, with 1 tsp of sphere cider vinegar, n they drink it, without even knowing..
Its the best way to prevent that crap. And a very healthy/cheap way.. Feel free ti drink it with water after u get the virus, as it kills on contact.
