"i&#039;ve been taking concerta for about 8 years and it&#039;s helped my mood and productivity a lot.  i used to get a stronger focus benefit from it and ritalin, so there are times i still feel unfocused.  but overall, it works well.  the one-a-day dose is great.  it doesn&#039;t keep me awake too late at night, unless i take it after 11 a.m..  i definitely notice the days i don&#039;t take it, either by choice or if i forget to get the prescription renewed.  the first day off it isn&#039;t bad, but after that i get really cranky.  so i like myself a lot better on it than off!  my wife does too.

it&#039;s not a miracle, but it definitely helps."
