It's when symptoms start to break through and it's time to change meds.

No one wants to be overmedicated and suffer more fatigue than they already do but... on the other hand, these symptoms can quickly escalate beyond the point of no return. That is what i mean by the slippery slope. What does it take to regain stability?

I'm currently facing disruptions in my sleep and having to change meds because of that.

The next stop is a spiralling catastrophe. There's . reason people are so scared of mania... If one crashes into a deep depression no one really cares unless you are suicidal, but if you are not, you can be depressed for years if not decades and literally no one gives a hoot about it.
