I have suffered from ADHD my entire adult working life. I am a developer and it’s been a real struggle. I could not utilize Adderall as I have high blood pressure and it hits your system all at once. Two years ago, a doctor prescribed Vyvanse. It’s been miraculous. I’m now able to function at a high level and maintain that performance throughout the day. I believe it restores your dopamine levels to that of a normal person. Vyvanse is a time release formulation that is also a single enantiomer (highly purified) and does not contain other undesirable chiral components of Adderall. Please look into this medication if you suffer from ADHD.
