[Harry Potter] If you ate chocolate while facing a dementor, how much would it help?

I've only seen chocolate used as treatment post-dementor. What would happen if you had it in your mouth while a dementor was attacking you?

It would be a bad idea. Dementors suck happiness out of you, chocolate makes you feel better because it makes you happy, replaces the happy you lost. If you got happier while a dementor was around it would just make it more interested in you.
