"after entering into a rigorous educational program where i am in the operating room for hours at a time, i realized i needed to see my doctor for my adhd. i first tried adderall xr. i had severe side effects, nearing a heart attack. i went back to the doctor and was prescribed vyvanse. i also have a history of anxiety and some depression. vyvanse has been amazing! i can focus and my anxiety is nearly gone. i will say that i had more focus with adderall, but an unnecessary amount of focus. i feel normal on vyvanse, like i am not on medication. my heart rate does increase during the first couple of hours. i also have to time the dose just right or i will either not sleep or the meds will wear off too soon."
