"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"
