I am searching for info and have yet to find any on psych lit re:
the affect of acetylcholine on one's thought processes. I've read
[but without citations] that a cholinergic dominated brain/mind
state results in loss of reality testing and loosening of
associations. Is there any experimental evidence of this, and if
so, how would it work.
The literature on this topic is very extensive, but you might have
better luck searching on MedLine than PsychLit. The hypothesis you
state is backwards, though. There is plenty of evidence that
scopolamine (sometimes known as "truth serum") and other
anticholinergic drugs give rise to amnesia and delirium, including
loss of reality testing and loosening of associations. This was known
as long ago as the 1950's.
