Bupropion added to a stimulant: does that combination actually make sleep better or worse?

Bupropion tends to push in the same direction as a stimulant rather than counteracting it, which surprises people who assume adding a second medication automatically means added sedation. It works by inhibiting reuptake of norepinephrine and dopamine, similar in spirit to how stimulants work though through a different specific mechanism, and it's commonly associated with its own insomnia and activating side effects rather than sedating ones. So combining bupropion with a stimulant is generally more likely to compound sleep difficulty than to balance it out, particularly if either medication is dosed later in the day. If the change is persistent, distressing, or affecting daily functioning, contact your provider through the FasTreat portal rather than changing medication on your own.

Added bupropion for mood alongside my usual stimulant and my sleep, which had been fine for years, got noticeably worse within the first week. Nobody had specifically warned me both medications work in a similar stimulating direction, I'd assumed adding something new would just be neutral for sleep at worst. Moved both doses earlier in the day and that helped considerably, though it took actively asking about it rather than the connection being mentioned upfront.
