Dexmethylphenidate
"I never had ADD or problems focusing and staying motivated before I had chemotherapy for Ewing's Sarcoma at 16-17 years old. I'm now 24 and started being treated for those symptoms with Focalin XR earlier this year. It was night and day difference for me. I had energy, yes the first week I was shakey but that stops, I lost weight gained from conituning to eat like a weight lifting football player but had very little movement at all. I felt great, I can get things done now. Motivation is now just lacking from my lack of trying but when I get on something I blaze through it. Negative effects I have experienced are occasional moodiness, especially if I am focused on something and then get interrupted. Caffeine is a no no."
