The trick might end up being alternating a day of 50mg Elvanse with a day without it because I'm pretty sure I've managed to make the effects of a single pill last MORE than a day and there lies the issue.
I took none yesterday, I felt slightly more ADHD me, but still very Elvanse-ish.
(before you ask, consistent L-tyrosine supplementation + a SAD light I only turn from time to time is the answer)
