"I'm 17 and have been taking 18mg Concerta every day for a week and a half. This is the second medication I've tried after being diagnosed with ADHD (I was also diagnosed with major depression). First I tried Adderall, and while it made me feel very alert and productive, I could not handle the severe depressed feelings from the comedown. So far Concerta has made me feel productive and positive for about 3 hours, and then depression slowly creeps in and gets progressively worse for about 8 more hours. It's not as intense as the depression from Adderall (which even led to suicidal thoughts), but it lasts longer. I also become irritable, anxious, and tired. I've also lost weight because trying to eat makes me feel queasy."
