Oh wow sorry this was back in 2011... Holy
If he can't stay off the vyvanse that is great as it is addictive and causes physical and psychological dependency.
I myself was just perscribed Vyvanse and I have been on clonadine for almost a year now. If I take clonadine steady for a week and then don't take it, I really notice a difference. It's mainly pounding heart rate and a hot face. Hope this helps
