Better then Insomnia

If you have a quantum system undergoing decoherence what happens when it reaches a point in which its changed or whatever, but is no longer experiencing any environmental push to continue to change?

Would the system just oscillate about through a finite range of possibilities, would those possibilities be deterministic and why? I mean water going from solid to liquid. If you could get down to the smallest quanta of energy that could change the bulk behavior of that matter in terms of its state, would it at that scale somewhat shift between being a liquid and or a solid, or would it just stay in one or the other until the environment changed it?

Lets say a particle can be A though Z on observation and is something quantum mechanical in nature.

If A decoheres to B, will it just stay at B for good as long as the environment allows, or will B itself change spontaneously?

I am just wondering because I have a speculation about entanglement. If a particle decoheres to a environmentally preferred state, when in that state I imagine quantum weirdness in terms of the uncertainty principal does not vanish, so I would imagine that such a particle would oscillate basically. But being the math used describes such bodies places them in a superposition of states, does superposition itself like entanglement and the uncertainly principal all tie into something more fundamental about quantum mechanics that maybe decoherence might hint on?

Basically its asking if environmental monitoring produces things such as entanglement, superposition, and the uncertainly principal. How could a quantum body such as a single particle ever be deterministic in lacking uncertainty if its but one drop in an ocean of quantum weirdness that suffers from entanglement.
