adhd
"I am 20 years old and I've been taking focalin for a year now. I have been on every ADHD medication under the sun since I was in second grade and this is the only  medication that helped me get on track right away. The only adverse side effects I experience are a faster heart rate (most ADHD meds do that) and trouble sleeping. If you are having trouble sleeping on this drug here's what you do and here's what I did: prior to now, I was taking my medication at 11am or 10am. Often I would spend nights awake and panicky just begging for sleep to come. This is a simple fix. Just wake yourself up at like 6am every day to take it and you shouldn't have any problem sleeping. That's what I did and I sleep very soundly."
