Ya even 300-600mg makes me sedated (don't ever do that. You will die. Just a stupid thing I did)

Most people with ADHD (like us) don't have the "amphetamine euphoria gene" and get sedated by ritalin. Ritalin is a calming stimulant. They even wrote on the bottle for me, "May cause drowsiness". Lol it's a stimulant but for us it's a calming stimulant. Also, I weight 150lbs and take 15mg. Maybe you would benefit from 10-15mg because 5mg is the lowest dose.

If not then try adderall. 25% of the amphetamine is the left part of the molecule which is more stimulating. It depends on if you need to calm down or be kicked by adderall. For me I'm hyper so ritalin does it's job as well as keeping me awake.

If you yawn then it means you're taking too much because that's a response of having too much dopamine in the brain at once.
