Info-nebriated 

When one has brainstormed or learned as much as their mind will allow and it gets overloaded causing them to act stupid for the rest of the day. Info-nebriation is characterized by an inability to comprehend simple concepts, giggling at inappropriate times and stumbling through a workplace or school.

The boss ended staff meeting early because the whole staff was info-nebriated.
