I was recently diagnosed with ADD and I was prescribed Concerta 18mg. The first day it felt like a huge difference, as though everything had been smoothed out a bit! I worked on things, cleaned a little bit, and wasnt as irritable as usual. Basically I felt calm all day. However, today is the second day taking it and I dont feel anything! I am irritable, hyper, distracted, etc. Does this mean that my body has gotten used to 18mg already and that I need a higher dose?
