I'm not a doctor but I sure am (sadly) an expert on sleep deprivation. Give or take 4 flipping whole years of it. Don't be fooled by the picture above, they nodded off together but were soon moved to their own beds and both woke up at least twice that night. Le yawn!
PMT is of course the aptly named tense period before your ERM actual period.
