yeah you're body was craving more of it...you'll get in that mode where you can't sit, stand, lie down, all fidgety (never actually seen that word spelled lol), it's crazy...sometimes that would even happen to me when i was soaring high on that shit...just feel like i was coming down all of a sudden, usually doing something fun would help, but sometimes i couldn't keep interest in anything, which is the opposite of what it does for ADD and ADHD kids...
