ADHD
"After a few days on vyvance I started sleeping only 2-4 hours a night, then my doctor raised my dosage, now I was on 30 mg. And then a few weeks pass and I started to get really aggressive, yelling at people when I got just a little mad (like if someone accidentally bumped into me while walking down the hallway)

And if that wasn&#039;t bad enough, I still couldn&#039;t focus in school.

and the longer I took it the worse my sleep pattern got. I started staying up about 40 hours at a time and sleeping for about 8 hours, And then finally my parents decided to take action and take me off of it.

it took me about 7 months to get back to sleeping on a regular schedule"
