Yes, those are likely withdrawal symptoms. The dopamine theory for schizophrenia suggests there are different dopamine receptors with different affinities for dopamine. As you wean yourself off the anti-psychotic, you may find dopamine levels increase, particularly at the dopamine D2 receptor. Another factor that comes into play is the specific medication. There are different potency levels of risperidone/Risperdal but in general, it can be a moderately potent anti-psychotic, although there certainly are several others that are much, much more potent, particularly your benzodiazapines.

Generally though, doctors are uneasy when a patient is off of their anti-psychotic medication unless they allowed it. Some patients go off of it because some of the side-effects are unpleasant, however, I gather your reason may be different as you said you dislike the idea of being on an anti-psychotic. Can you explain why you dislike it?
