Best ways to deal with the stomach flu?

you could have a urinary tract infection they will make you sick like a stomach flu when i had one it lasted for a week all i could do is drink tea its the only thing that made it feel better i didn't go to the doctor or anything but all i did was lay in bed and sleep and couldn't eat anything at all not saying that is what you have but it sounds like the same symptoms that i had i thought it was the stomach flu myself if it is a urinary tract infection you can get medicine from a doctor
