I am taking Sertraline 100 mg 1-0-0 and Mirtaz 15 mg 0-0-1 for mixed Depression-Anxiety and Sizodon plus 0-0-1 and Sizopin 25 mg 0-0-1 for Schizophrenia since 10 years. There is relief. Now, I find it difficult to stand or sit for a long time and hence I have the urge to lay down often. Do anti-psychotic drugs act on the brain and the spinal cord which causes the urge to laid down often? If so, what is the condition called? Is it Irreversible? This is coming in way of my everyday duties. Please confirm with specific answers to the above two questions. Thank You.
