Hey doc, I just started taking vyvanse (30 mg) again for the first time sense high school three years ago. I started taking it again because I will start school again in January, but in the fall I'm trying to Play football and I need to put on size for the season. I was wondering if the vyvanse is ok to do hard weight training with cardio? I do mostly sprints and footwork drills. Also will it be challenging to gain weight? I'm 165 now and I need to gain another 15-20 pounds by next fall. I have trouble eating on it but i have been trying protein shakes. If it's possible to gain weight on vyvanse how should I do so? Thank you a lot for your time.
