"i take adderall for adhd, simply put my gpa in college has literally doubled to 3.5, school is easy now. this medicine is like night and day. i&#039;m glad it only lasts for a certain time 6-8 hours. i have zero appetite on the medicine and lost 15 lbs in two weeks when i started these pills. aggression is increased. adderall is amazing. listen to your doctor and do not take more than you are supposed to."
