"i have mainly taken 36 mg doses of concerta from middle school through 25 years old. i start the morning with 10 mg ritalin then take concerta 3-3.5 hrs later. due to its appetite suppression, i come home weak from hunger after 9 hrs of work, but my mental focus keeps me going and i get irritable if something gets in my way. if i give in to my weakness, i will slump on the couch and think about all the things i need to do. i never fully rest mentally, though it alleviates some of the hyperactivity. i have severe adhd that affects my friendships, marriage, and helpfulness. my aunt switched to adderall from this because it helps you initiate tasks, which concerta doesn&#039;t. i will try vyvanse, which is extended release adderall."
