"my 8 year old was diagnosed with adhd this year.  we tried a non-stimulant first (guanfacine) but it didn&#039;t work plus she was soo sleepy on this.  switched to 30mg of vyvanse and instantly her grades &amp; school performance increased.  she also plays sports and has improved due to better focus.  we constantly had to yell out into the softball field to &quot;be ready&quot; prior to the medication.  now, she&#039;s always ready to go.  side effects to begin were insomnia for about 3 days.  dr. suggested 2mg of melatonin which worked fine.  we did melatonin for 2 days then she was back to falling asleep on her own.  weight loss is also an issue.  she&#039;s down about 6 lbs but she&#039;s tall 4&#039; 7&quot; and weighed 94 lbs.  i don&#039;t give it to her on the weekend and she eats ok"
