Do they get better? She has had two pills. She said she did get her work done at school, maybe a little better. However, she also has NO appetite, didn't sleep much, is tired tired. I wouldn't think Concerta would make one tired, but I know it is doing so. She is normally peppy (not hyperactive, but peppy) and she looks really tired today. Although she can't sleep. Do the side affects go away or is this how it stays? She is only on 18 mgs. She is supposed to take it a week, then fill out a form about how she feels. Then she is supposed to up the dose. Etc. I asked her how she felt and she said, "Tired." I said "Are you more alert?" She shrugged. Any insight? I know this isn't a drug that builds up in your system.
