I figure it should go away without any food. I've had enough of these infections to know usually days in advance. I'm also in-tune enough with my body to know exactly when something feels off. There's also the water cup test, which is where you spit into a glass of water to determine if you have that infection. Tends to be pretty reliable for me. But to be fair, I didn't try that test earlier this week when I'd thought I gotten rid of the infection.
