She sounds like my DD8. She is like a while tornado in her natural state! (Which is where we are at currently, we had to stop the Adderall due to ticks.) Off meds she's not only hyperactive and impulsive, she's more moody - high and low. Crazy manic cackling at stupid/silly thing, falling apart crying crocodile tears over being told no, etc, etc.

I think it's a combination of their age, and the complete lack of control over their impulses when they are unmedicated.
