I try to call and ask directly if I am calm enough right after the appointment to clear up or at least clarify in order to keep the anxiety down. That is usually once every couple of months.
I email in order to get rage and frustration away from me after the appointment if I think it will keep me from excessive si. That is about once every three or four months.

I usually am in a frustrated rage after every appointment but only contact the therapist if I think it will help dissipate some of it so the si is not so bad.
