Ritalin is a chemical relative of amphetamine. In prescribed amounts it's often an effective treatment. In recreational amounts, ask your doctor about ΔFosB:

I was unaware that Ritalin is used as a recreational drug.

It's a drug that is often diverted by people who have a prescription in order to make money.

Well, I'd say lots of words for how horrible and terrible it is to have Mr. Jekyll and Hyde around. Any specific questions?

I don't know enough to ask specific questions. I could consult with an LLM, but if there is some risk or side effect that doctors do not typically mention, I'm all ears.

In that case I guess I could caution this: if you have any kind of OCB, our experience is that prolonged exposure to Ritalin will multiply it by at least 10.
