Doing a lot of things that require your brain.
Tomorrow has to be all business. 10am office hours for chemistry, then study 3 chapters of psychology. I’m going to be so brained out.

The inability to remember literally anything in the last few weeks leading up to the wedding. The Bride's brain feels like it was actually removed from her head, and fried (scrambled egg style). She starts speaking nonsense ideas and repeats herself multiple times since she can't remember who she told what to. Symptoms include but are not limited to: bad wedding dreams, waking up at ridiculous hours of the night and not being able to fall back asleep, forgetting to eat, rambling on about nothing, uncontrollable laughter at random things.
Mother of the Bride Brain can also occur in a similar way. If both the Mother of the Bride and the Bride get this, LOOK OUT.

I'm afraid Kelsey has Bride Brain. She told me 6 times in a two hour span that she still needs to start packing for her honeymoon. I'm also worried about her mom, DiAnn, she laughs hysterically at almost everything.
