Talk to him about giving it a try with an agreement (in writing) ahead of time that if he feels “numbed out,” you can try a different medication or stop altogether. He might be willing if he knows he doesn’t have to continue if it slows him down too much where he can’t be himself.
And, when that happens, it’s because it’s the wrong medication or too high a dose. Make sure he is always started on the very lowest dose.
