I can identify with that, I'm currently on 20mg ritalin sr (generics) after just giving up without meds. To this day, if I am interested in the subject I can focus like crazy, get everything down. But if its something I'm not interested in (ie. binomial distributions) I just space out and day dream the whole time. I've only been taking rit for the past 3 weeks, but have definately noticed a difference. I'm simply a much happier, more active person today. I can concentrate on things without someone clicking their damn pen distracting me to hell. Surely, it is not a cure, but a simple aid.
