"i was diagnosed a few months ago (i&#039;m 19) with add. the first--any only-- medicine i have tried thus far is concerta (27 and 36mg). not only has my add not gotten any better, but i feel i have anxiety, mood swings, restlessness, and insomnia. i&#039;ve used it for several weeks, adjusted my dose, and minimized any external stress and it&#039;s not any better."
