For me, I get super creative and involved in my music. I'm a musician, and once I recorded a full length album overnight (just wrote the music and lyrics, and recorded 50 mins of music. My friend was in shock that I put out something that creative and good in only 1 day.)
Also, I will obsessively clean the house. I'll get all sweaty, but feel so high that I'll barely even feel tired. That is, until I come off the mania, in which case I'm exhausted.
