What is the ruling if one performs an excessive amount of eating or drinking during a voluntary prayer?
Chapter on the Two Prostrations of Forgetfulness
Al-Mughni
Book of Prayer
Primary text

This is because non-eating actions invalidate the prayer when done excessively, meaning eating and drinking are even more likely to invalidate it under the same condition.
