@alex921, Chronic amphetamine administration causes disinhibition of the PFC, or basically poor/very reduced GABA signalling. Also you bring up D-cycloserine, which is a partial NMDA agonist. I am currently taking sarcosine, which increases the amount of NMDA co-agonists (NMDA and D-serine) by inhibiting the GlyT1 glycine transporter. Drugs of the same class are being developed for treatment of schizophrenia and OCD. Sarcosine has the same benefit but can't be patented.
I have had extreme success with sarcosine. I regain fine motor control and normal cognition when I take it. Apparently it ameliorates ataxia by intereacting with glutamate receptors and indirectly with dopamine receptors in the cerebellum. The ataxia has been unspeakably bad and this is the only thing that has helped it.
OP, sarcosine could potentially help you, as you did mention motor control issues. It also greatly helps with cognitive problems and will reduce or completely negate any residual psychosis or psychosis-like symptoms (irritability, confusion, weird body sensations, etc)
Also, I really think tetrahydropalmatine is worth looking into. It's a natural dopamine antagonist that works as a very effective anxiolytic and sleeping aid, and should encourage dopaminergic upregulation. I've currently been helped the most by sarcosine and bacopa, but I still feel a long way from normal. THP is next on my list to try.
Also, I want to note that the guanfacine is complete garbage and the somatic side effects far outway any psychiatric benefits. I also tried prozac and had a severely bad reaction a few days in with guanfacine and focalin which caused
extreme tachycardia, ataxia, inability to control my muscles, weakness, etc. It was literally the scariest thing I've ever experienced. I have zero motivation each day, so I have tried to take the focalin a few times but it just makes me really really sweaty, anxious, fogbrained and irritable, and oddly makes me have to poop immediately after I take it. Vicodin has helped but I can't go down that path. I tried to pickup smoking again in hopes it would help but it just made things worse. I even tried cannabis a few times again but was extremely sensitive and it brought back the exact same sensations of MXE, however this didn't happen when I took sarcosine beforehand.
So maybe try looking into THP and/or sarcosine.
