The medication doesn't interfere with the Plan and vice-versa.
The cheats feed the fungal candida while you're trying to eliminate it, and can create excess mucous production which may last for a day or two or three or four, depending on the reactivity of your tissues.
If I were you, I would start over. I wouldn't say that you cheated. I'd say that you're not following the Plan. White rice, whiskey, corn bread, black-eyed peas, peach cobbler, bacon, pecan cake, and lemonaide mix aren't on the Plan. I'm not sure what you meant by sweet tea.
