Similar situation, started on Concerta which worked great, but then I built a tolerance to it. Tried lots of meds since but nothing has worked. The adderal family didn’t help much and some really messed with my pulse. The Ritalin family seems to be affected by my tolerance to Concerta. I’ve tried Wellbutrin now as my first non-stimulant but it doesn’t seem to be doing anything. I actually see the doctor this week to figure out our next steps.
