I know this is new, but has anyone used this medication? A co-worker's daughter started this and it has been a miracle drug for her. Since she and my son have some similar issues and behavior (like other ADD medications not really working, mood swings) we talked to his psychiatrist about trying this. The psychiatrist thought it was worth a shot. She gave us a packet with info and a number to call to get a free 30 day trial. Has anyone used this? What did you / difficult child think of it?
