Tangentially related: If anyone's ever worried about an infection but you don't want to go to the hospital, buy some FRESH garlic bulbs and eat 4 cloves a day. (The cloves are those little petals you pull off and peel, don't eat 4 whole bulbs.) Just chew it and swallow it. It'll taste like shit and burning, but there's a reason they called it "Russian Penicillin" in WW2.
Of course, everyone poor enough to already know this tip will immediately realize you're staving off an infection, because if you're eating enough, you sweat will smell faintly like garlic.
You can greatly reduce your garlic breath by chewing up a mouthful of iceberg lettuce, but spit it out. Don't swallow it. Lettuce has enzymes that neutralize garlic-smell, but they also neutralize its antibacterial properties.
