A methylphenidate used in treatment for ADHD. When diagnosed and consenting to meds, you go on a drug trial to figure out which dosage is best for you. Concerta XL 18mg-27mg-36mg-54mg-72mg, and if none work, Docs should prescribe another medication. Lemme tell you, the smaller doses aren't as effective if your brain is more fucked up.
I started feeling the side effects more at 36mg, and at 54mg my eyes started burning and shit started becoming blurry. Felt like I couldn't read a motherfucking number plate.
Anyway, your heart rate becomes fucked. Increases to some stupid number. Boy, i was a normal 70 bpm before and on 72mg i'm at roughly 109. Be prepared to feel anxious, agitated, and lose your appetite.
That's the shitty side though.
Your concentration does improve if you're on the right dose, and you actually don't want to procrastinate as much anymore. I'm sure you'll be able to talk in actual sentences too and stop feeling like a damn numpty whenever you try to explain something.
Need to take my concerta before my lecture, otherwise i won't understand a damn thing.
