Is it the Ritalin, or the Gold Stars?

Here's my September so far, the gold stars showing days I've written 300 words or more on my dissertation. Earning gold stars is addictive—or is it the Ritalin? I was able to get a refill of my prescription early and have been taking 15 mg/day. That's still not very much, but it's more than the 5 mg I was taking per day before, and I think I feel more alert. I think so. But then, I am tremendously susceptible to the placebo effect.

As you can tell, Ritalin is not preventing me from indulging in time-wasting activities like blogging.
