Do you eat as usual on the day of the Maunzaro?

While looking up Maunzaro, I suddenly became curious.

It seems like everyone has a different method on the day they get an injection, whether they eat as usual or intentionally eat lightly.

Especially when you are just starting out, you will likely be concerned about your diet as well, since you don't know how your body will react.

I'm curious how those who actually started with Maunza ate during the first week.
