They can for some people on some days or parts of days (my anxiety peaks when stimulants are wearing off). But like the other poster said, its more that they do nothing to solve it. I found a beta blocker in addition to stimulants was good at unlocking my productivity. YMMV.

Additionally, the boost in dopamines rewards anything you happen to be doing, so it can lock you into your avoidant behavior that day once you start doing it.
