"My 10yr old son has been on Vyvanse for 1.5yrs. Worked GREAT in the beginning. Grades, handwriting, organization and attitude improved. I worry about long term effects. I just recently noticed a change in his behavior. Getting grouchy, irritable, not focusing &amp; his grades are falling. I give him &quot;breaks&quot; during x-mas vacation &amp; summer. However he has side affects from getting off &amp; getting back on that are scary. He starts hallucinating &amp; wants to hurt himself. Its been 2.5mos since he has been back on after summer break. It just doesn&#039;t seem to be working like it did before. I am trying to adjust his dose while working with his Doctor, but I don&#039;t like the effects. I would love to take him off for good but know he would struggle even more in school."
