honestly, I prefer a movie more like momento, but I have not seen limitless. sorry to hear that you are struggling so greatly with ADHD, time management, and our health care system alone in general, but it seems you have made your decision to not seek medication for this problem.

I encourage you to reconsider what ss has suggested
