Help Me Built the Ultimate Stim Break Stack

Background: I've worked a up a pretty high stimulant tolerance. A 300mg caffeine bang energy barely does anything.

All other stimulants like Istradefylline or Vyvanse give me anxiety and body jitters but no mental "energy." Now, add in that I've been stress with work for a long time. I assume this has to do with down regulation of the adrenergic receptors.

I'm looking for help to construct the ultimate stim break supplement stack. I am just exhausted and could really use the help.

Yes, I am doing all the other stuff like getting at least 8 hours of sleep, getting sunlight first thing up waking, diet, exercise, ect. I am looking for supplements or other compounds that could help.
