If you're borderline, talk to the doc about a trial of guanfacine. (note that some people HATE it, for exactly this reason) It's the opposite - if your engine is always redlining, it sets a rate limiter and gives you the chance to look out the window and enjoy the scenery, metaphorically.

And in the most interesting cases, you can find a lot of value in both - stimulants keeps you going, guanfacine gives you perspective and the ability to unclench.
