My feeling is that alcohol would negate any work put into doing the protocol. This is just from my experience, but ingesting anything that “feeds the candida” (sugar, gluten, alcohol) just makes my symptoms a lot worse. I haven’t been able to beat candida or leaky gut syndrome yet, and part of the reason is because for years I’ve been constantly cheating with the diet. Drinking alcohol would be kind of like trying to beat cancer but continuing to smoke.
However, I know from experience how difficult it is to stay on such a strict diet, especially in social situations. I have a friend who doesn’t completely understand my situation (and apparently doesn’t want to) who is constantly telling me “you can cheat” when we go out to eat, so I don’t really hang out with her anymore. I’ve pretty much come to terms with not having much of a social life while on the strict diet! So, if you really need to have that drink, the only thing I can suggest is to pay careful attention to your body, perhaps not drink at all for a week or two, and compare your symptoms are to when you do drink. Then you can decide for yourself if your body can handle it and if it is worth it.
