I read that wine and oil are allowed on Wed and Thu of the fifth week for the vigil of the Great Canon, and wine is allowed on Fri for the vigil of the Akathist Hymn. Should you only consume wine and oil, then, if you actually attend these vigils, since it doesn't seem to be a case of relaxing the fast in honor of a saint, but only for sustenance?
Also, what are you meant to be eating otherwise if a little wine and oil makes such a difference? Bread and water? I guess this ties in to my general confusion about what exactly is allowed during 'dry-eating' days. Particularly, are boiled foods allowed or not? Does it make a difference what kind of food you normally eat?
The reason is I'm guessing how you interpret the rules depends on your normal diet. So, if you eat basically north European 'beer and butter' food, like most Americans traditionally, then you should copy the Russians, who seem to limit the fast to meat and dairy, and maybe fish and alcohol (excluding beer) on stricter days, but if you eat basically Mediterranean 'wine and oil' food, you should copy the Greeks.
