hi. sorry about this. clozapine has a well-documented "discontinuation syndrome." I guess since people on clozapine are to be monitored, there's more data on what happens when people stop clozapine than most other antipsychotics. anyway...
from what little ive read about it, your experiences line up with what's been observed in a lot of people, and honestly...that overlaps with the experiences people who taper off -any- antipsychotic often experience. :-(
i dont have any major suggestions, except maybe see if the doctor will provide some short term sedatives (benzodiazpeines, lyrica, gabapentin...anything to stay calm), since people tapering off psych drugs often report that sedatives at least help them simmer down and get through things...but that's just what i've read, clearly...its up to your treatment provider(s).
sorry about this. :-(
