Please do let us know if you feel more "dopaminergic" after you withdraw. This is exactly what I'm interested in.
Antipsychotics have been shown to upregulate dopamine receptors.I hear that the way a lot of anti-psychotics work they actually reduce dopamine and therefore make a lot of people feel numb because they don't work as a reuptake inhibitor but rather block dopamine production since it is believed to be the cause for a lot of the schizophrenia behaviour etc. I don't really know the specifics since I'm no expert, just what I have heard and read from other people.
In theory they should be reversible by using a high dose dopamine agonist to downregulate the receptors again.Taking a short half-life antipsychotic every night would probably work for this purpose, but apparently the movement disorders people develop from these drugs can be irreversible, so maybe not such a good idea.
