It can be due to side effects of clonazepam
which may cause Short-term memory
loss and Anterograde amnesia
(common with higher doses) - a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. While problem of speech may be due to clonazepam and olanzapine
. So consult with your Doctor openly regarding the problems. In my opinion, prescrbing doxepin, clonazepam, Prozac, olanzapine all at a time might not be needed.
