I took Ritalin. It made me want to sit and ruminate a lot. My mind felt very awake and activated, but not in a way that was practical. I wasn't really getting more done. Just doing a lot of thinking that served no particular purpose.

Also, I had to take a pretty low dosage because higher amounts made me anxious. I would feel a lot of tension in my face that went away when I stopoed the Ritalin for two days.

But it was effective at helping me wake up in the morning. Also, it was a strong appetite suppressant for me.

I've read that it can affect the mind similar to methamphetamine.
