Hi, I'm currently a sixteen year old senior, and i was diagnosed with ADHD 2 years ago. I've tried focalin, concerta, ridalin, ect. Finally a year ago I was switched to vyvanse. At first they started me on 30mg, then to 40mg, then 50mg. While on 50mg, i was happily able to control my adhd symptoms, however I dealt with insomnia, shortness of breath, involuntary ticks, and I began to pick my skin uncontrollably. After that, I was unable to handle the stress of the medication.
