"i too have gone through my whole life with undiagnosed adhd and i have to say that i have lost so many years of my life both academically and personal. i&#039;ve been recently diagnosed with adhd and started ritalin. i could not tolerate ritalin. it made me feel like a zombie along with bad headaches. my md switched me to adderall and it has changed my life. i wish i would have sought help years ago but i was too embarrassed to seek mental health help. i&#039;ve been on 30 mg per day of adderall for 1.5 months now and its worked great except that i think this dose is too low as i have to split the 30 mg into two doses per day. 20 mg works great for me but the other 10 mg i have to take doesn&#039;t do much for me."
