I have only taking adderall 10 mgs for one day and i totally felt a huge difference. Much calmer, anxiety has lifted i am not only starting taks but finishing them better without the stress and overwhelming anxitey. I like this medication but i feel its just a pinch of what an increase to 20mgs xr once daily will do for me. Does anyone have any advice or ever felt the same way early on when starting Adderall??? Please let me know!!! :)
