I lost a TON of weight on Vyvanse... I moved about 7 months ago and only JUST got put back on Vyvanse. Within the first month after moving I gained 20 pounds... I am wondering if it is possible to loose all of my weight again since I have just gotten back on Vyvanse? How long do you think it will take? I was at 110 pounds and now at 130.... Trying to get back to 110?
