I'm A Grandparent, My Grandson Has Been Diagnosed With Adhd Since He Was 6 Yrs Old. He Is On Medication And Everytime He Has A Behavior Problem His Medication Dosage Is Increased. He Bites His Tongue And Lips To The Extreme That He Makes It Bleed. They Call This A Tick. Can The Medication He Is Taking Making Him Do This? I'm Very Concern About Him. He Is Going To Be 10 In July But He Is Very Thin, Eats Poorly And Doesn't Get Much Sleep. Please Advise.
