"since i started taking 15mg of adderall xr about 2 weeks ago i feel like it&#039;s changing my life for the better. i can&#039;t say it is having a huge impact on me but i can definitely notice a difference when i&#039;m on it as opposed to when i&#039;m not. my concentration has definitely improved. i can stay on the same thought pattern a lot easier and also follow through with the task at hand. i feel more aggressive towards events that happen it definitely gives me a different outlook.the only symptoms that i am getting with adderall xr is a loss of appetite. it&#039;s really strange how i went from having a huge appetite to just not even thinking about eating or making it a priority. i don&#039;t like it but it saves me a bit of money."
