I have the same problem and I was on the medication and now I am off, why?
It was slowly killing me, I almost lost my humanity and I had a pale white skin and it screws up hormones in general. You feel great once you stop.
But I suggest not taking it unless you really have to, like for the week or for the day, but not consistently like I did everyday of the week for 52 weeks a year for 10 years.
But one can teach ones self to concentrate and plan and organize.
Also you earn and learn skills, It doesn't fall out of the sky. So just learn to plan and organize. Or make them link to your obsessive interests if you think it is possible.
