ADHD
"I am an 18 year old male. While I was in school I struggled with subjects that involve high levels of focus to succeed in e.g. Math, Chem, Physics, English (all of the important ones). In grade 12 I decided to try Concerta after a bad experience with Ritalin (night terrors). I only take it on days I will need it which I think makes you not need to go up in dosage. It worked so well it is hard to explain what happens exactly but it just makes you focus and understand what the teacher is talking about. My marks instantly went up. The only side affects I get is I feel warm and sometimes if I take it to late in the day I have trouble falling asleep. This medicine is a miracle, I wish I had it earlier on in school because it helps so much."
