MS, 22 years, Provigil / Nuvigil just not effective > 2 hrs, what is next ? Adderall ? I shut down around 1-2 PM, having an effect on my work quality, and this NYC heat is not helping. It has never been this bad. Would a next step med be Adderall, Ritilan, etc. Should I be afraid to take due to addiction issues with those meds ?
