Not to intrude but I highly recommend you “play around” with longer acting ADHD meds. Generic short acting Ritalin is the worst. It doesn’t last long and you can “feel it go away”. There are much better meds that have the same underlying drug but in much better delivery mechanisms.

I’m sure you’ve done the homework but if anybody is reading who hasn’t… if generic short acting ritalin works, great! You know you respond to stimulant adhd meds. Now go find a better long acting one… focalin xr, adderal XR, vyvanse, etc…
