Personally, I found the promise of XR's delayed-duration to be massively overstated. I like the IR's better, because you can figure out when to re-dose through experimentation (which my doc encouraged.)

I was also motivated to change to IRs, and mentioned to my doc, that the generic IRs can be had for less than half what generic XRs cost, with GoodRx. I have insurance, but GoodRx is cheaper, and insurance gives me runarounds with 'prior auth' nonsense.

My timeline was a month before switching meds/doses. Obviously, you want to give it an honest shot of a few weeks, but if something isn't working after a month, your doc should be willing to change it up. If they're giving you a hard time, I'd explore other options. There seem to be a number of providers that have a prejudiced view of stimulants. If you needed to switch/increase the dose of say, an antidepressant, no doctor would think twice.
