Your PCP is the tier-1 tech support of the medical world. They have basically zero specialized knowledge to evaluate different medications outside the brochure the sales rep gave them. There's a reason PCP's punt the responsibility for a diagnosis to a psychologist and then play the game of "spin the wheel of stimulants" to find something that both alleviates their symptoms and has tolerable side-effects. Having to go through the process all again for no reason other than weird politics or a doctor on a power-trip is the worst.
Ugh.
