adhd
"I had a great experience with this medication.  I had to go off all medication for a while but will ask for this again when I can resume. My doctor gave me Concerta and I didn't think it was doing anything.  I felt calmer, the way you feel after a well rested vacation, but that was all the difference I felt. THEN my co-workers started complimenting me on my work more, saying I was doing much better (They were the ones that suggested I get tested for ADHD)."
