"I am a 15 year old female. I started taking Vyvanse around 5 months ago. When I first started taking it I saw a difference immediately. I was always on 50mg. It made me very irritable and emotional the first times I took it. Currently, I've been taking this for a few months and it is starting to become less effective on me. I am now starting to double up my doses taking 50mg to 100mg a day. It gets me through the day and keeps me awake. Not to mention excellent grades in school."
