For starters, I managed to play a new videogame for unhealthy amounts of time the last 2 weeks with such dedication. We're talking about waking up to turn on the PC and look what I have to achieve in the game for today then get it done. I never felt like something would make me get up other than food and toilet. Second, I managed to quit smoking cold turkey, after a decade of heavy smoking. I can't feel like I'm a victim of my own craves or I lack the power to just sit down and get things done. And yet, I do identify myself in the OP's blog post.
Would you suggest that I should still take the ADHD test? If yes, which doctor can I ask about it?
I struggle with attention issues myself, and have tried medication, but have noticed a difference in creativity when medicated (although much more productive). I'm an illustrator as well as a programmer and find those two interests not always working the same way. Maybe I just need to try something different (I was trying Ritalin).
