"i have been using concerta for about 3 weeks now and it has changed my life drastically. i am a film writer and director and can already tell a difference in the way i am filming, my co-workers as well can tell. it is awesome! the only side effect is that i am less hungry, which is okay in my book or in any other womans book. it is not a horrid loss of appetite but still, i have loss 5 lbs in 3 weeks. which again is alright. ;d"
