The Medication is meant too help main symptoms, like depression, finishing task, increase self esteem. I have found alot of people don't do good on concerta, or Ritalin.I took both at one point so . Studies show Vyvanse is more effective in adults with ADHD and I was on it and really helped me alot, but after a year and half it stopped lasting long enough it use to last 12-14 hours one dose in A.m. my doctor switched me too Adderall 20 mg 3 times a day this way I have more say in how long it last cause I can take right before I got to do some work or say going out with woman , basically I take when I think I should be at best too learn and retain information. Anyway I'm 40 but I was diagnosed at 6. Seriously check Vyvanse.com it's got all info including the test they did too get it approved it's impressive .
