Wow, I didn't realize it had been almost a year until you said that!
Yes, I'm still on Ritalin--in addition, I found out that the night panics I'd been having (which I mentioned in that post as well) are actually sleep apnea. Turns out, when you can't breathe at night, you often wake up in a panic. Who'da thought? :)
I normally take 1 Ritalin per day now, instead of the 2 I've been prescribed. Days without it are still less productive than days with it. The biggest change, though, has been understanding how my ADHD ties in to just about everything I do...it was why I couldn't connect with people, why I had trouble getting things done, and why my productivity never seemed to be where I felt like it should be. (The whole "should" thing is a trap in and of itself, but that's a different post for another time.)
I vastly prefer Ritalin to Adderall since the Ritalin doesn't give me the "narrow focus" issue I complained about with Adderall in my 2006 post. Ritalin is generally considered to have more mild effects than Adderall, and different people react differently to them.
