The thing about hypo/mania and psychosis is that the person having it often can not remember just how bad it is.

From your description I would not consider you as being mild. But that doesn’t mean you need snowed under with meds , who wants that ? No one I know.

I think you can approach your Pdoc and T and come up with a plan to slowly wean off one of your meds and see how things go ... you first need a slow taper, every med has a half-life that needs factored in and then your brain needs time to go back to working sans that Med, years ago I went off lithium, it sucked for me. But honestly my brain didn’t really go back to functioning on its own for at least 3 months.

So talk to your Pdoc, as long as you go very slow and have a plan in place that if you suddenly start to have X symptoms you can get right in to see what adjustments are needed.

All along the way you need to be actively using coping skills, good healthy foods, sleep hygiene, exercise , certainly track your mood daily, you can catch an episode coming before your in the middle of it.

Just be honest
