"double edged sword with adderall. great for concentration, brought my college gpa from a 2.5 to a 3.7, amazing. although i do have trouble sleeping with it, and i often have mild bouts of depression, and roller coaster of emotion that i never have had before. although it is important to state that this may be because i am not eating as much and forget to eat, which could easily cause these symptoms. amazing for athletics, i am able to run 3-4 times farther with this, really great. a nice feeling when its working and with  a definite comedown. its important to mention i am on the ir version, which could be causing these side effects. my food habits are also now very healthy."
