Yes, I think it can be a problem. Sometimes it's hard to tell what med is doing what and there are doctors who just add and add.

I feel like I had that problem with a previous doctor. But with that doctor it was more putting me on a ridiculous dose of a med which ended up causing me to be in the ICU with severe Lithium toxicity. Lithium was clearly not helping and she just kept increasing and increasing till it literally started shutting down my kidneys. That's not common and most doctors would recognize the signs long before it got to that point, so I hope I don't scare anyone.

I'm happy with my current doctor. I've been on the same meds for a couple years. One was added recently but other than that the meds were adjusted in dose and if needed switched out.
