"my first day taking it, it made me so angry i would pace around and cry. i had to be moving constantly. my insides felt like they were churning, like i had to burst out of my skin. i couldn&#039;t sleep either, it was hard to sit and watch tv, read, or play video games, or even to stand still in the shower. essentially, i was up pacing around for about 20 hours a day. i have never had such an experience before."
