I know exactly what you mean, Scrooloose. I get exactly the same thing on stim psychosis and it really doesn't matter if you tell yourself that nobody is really interested enough in you to monitor your activities cos there's irrefutable evidence of the fact they are doing exactly that at every turn. Have gotten myself into some right states on stims (well, on peev anyay).
In my situation it was purely the drugs and lack of sleep that did it - I have no underlying psychotic disorders afaik - so as soon as I got some sleep and/or laid off the stims the symptoms all went away. I really do think you need to lay off the stims too. It'll stop the worst of the symptoms, I'd suspect. Maybe not everything but would certainly make things a bit more manageable. They ain't helping anyway as I'm sure you must know.
As for antipsychotics, I also know exactly what you mean. Horrible things that just mong you out, knock you out and leave you braindead. No fun at all. But if you were to lay off the stims you could probably ease up on the antipsychotics too. The stims just ain't helping at the moment. At all.
In the longer term you might just have to find a new DoC cos stims ain't your friend. I really don't know what to suggest (other than the obvious: no recreational drugs is probably best) in your situation but summat less prone to frequent/heavy abuse. Summat that lets you sleep more. A night of fun stuffs rather than weeks of paranoid delusions.
But you really do need to lay of the stims, I think. At least you'll know where you are with the underlying issues then and might well also be able to take less of your meds if you're not constantly exacerbating the problems that has you stuck on 'em. Take a pause for breath and see how it goes. It really can't be much worse, can it?
And good luck
